Vulnerability from variot
Multiple stack-based buffer overflows in the (1) send_dg and (2) send_vc functions in the libresolv library in the GNU C Library (aka glibc or libc6) before 2.23 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted DNS response that triggers a call to the getaddrinfo function with the AF_UNSPEC or AF_INET6 address family, related to performing "dual A/AAAA DNS queries" and the libnss_dns.so.2 NSS module. GNU glibc is an open source C language compiler released under the LGPL license agreement. It is an implementation of the C library in the Linux operating system.
There is a stack overflow vulnerability in the getaddrinfo function in glibc when processing a specific DNS response packet. An attacker can use the vulnerability to launch an attack on a Linux host or related devices by constructing a malicious DNS service or using a man-in-the-middle attack, which results in remote code execution and can be obtained. User terminal control.
This update also fixes the following bugs:
-
The dynamic loader has been enhanced to allow the loading of more shared libraries that make use of static thread local storage. While static thread local storage is the fastest access mechanism it may also prevent the shared library from being loaded at all since the static storage space is a limited and shared process-global resource. Applications which would previously fail with "dlopen: cannot load any more object with static TLS" should now start up correctly. (BZ#1291270)
-
A bug in the POSIX realtime support would cause asynchronous I/O or certain timer API calls to fail and return errors in the presence of large thread-local storage data that exceeded PTHREAD_STACK_MIN in size (generally 16 KiB). The bug in librt has been corrected and the impacted APIs no longer return errors when large thread-local storage data is present in the application. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

HPSBGN03547 rev.3 - HPE Helion Eucalyptus Node Controller and other Helion Eucalyptus Components using glibc, Remote Arbitrary Code Execution
NOTICE: The information in this Security Bulletin should be acted upon as soon as possible.
Release Date: 2016-02-18 Last Updated: 2016-04-29
Potential Security Impact: Remote Arbitrary Code Execution, Denial of Service (DoS)
Source: Hewlett Packard Enterprise, Product Security Response Team
VULNERABILITY SUMMARY A security vulnerability in glibc has been addressed with HPE Helion Eucalyptus Node Controller and other Helion Eucalyptus components. The vulnerability could be exploited remotely resulting in arbitrary execution of code.
- Helion Eucalyptus Node Controller (NC) components are confirmed to be affected by the vulnerability. Other Helion Eucalyptus components and pre-bundled service EMIs do not directly expose the vulnerability, but because glibc is a commonly used library on Linux, the exact exposure is hard to determine. Any software performing domain name resolution is potentially vulnerable.

SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.
- HPE Helion Eucalyptus Node Controller 4.2.2 and earlier

BACKGROUND
CVSS 2.0 Base Metrics
Reference Base Vector Base Score CVE-2015-7547 (AV:N/AC:M/Au:N/C:P/I:P/A:P) 6.8 =========================================================== Information on CVSS is documented in HP Customer Notice: HPSN-2008-002
RESOLUTION
HPE has made the following software updates and workaround information available to resolve the vulnerability with glibc for HPE Helion Eucalyptus.
-
All hosts running HPE Helion Eucalyptus services should be upgraded to the latest glibc. Updated glibc packages are available for RHEL and CentOS:
https://access.redhat.com/articles/2161461
RHEL Note: After following the guidelines for RHEL, a reboot is the safest and recommended way to ensure that updates takes effect for all services.
Workaround:
As a cloud administrator:
1) create an update-glibc script with the following content:
#! /bin/bash
yum update -y glibc
2) set the following cloud properties to use that script on instance start:
euctl services.imaging.worker.init_script=@update-glibc
euctl services.loadbalancing.worker.init_script=@update-glibc
This script will be automatically executed for each of the new instances started from the service image. For instances that are already running, the cloud administrator will need to terminate them and start again for the script to take effect. More specifically, for the Load Balancing service, the cloud admin needs to find all instances running under the "(eucalyptus)loadbalancing" account:
# euare-accountlist | grep loadbalancing
(eucalyptus)loadbalancing <accnt_id>
# euca-describe-instances verbose | grep <accnt_id>
And terminate them using euca-terminate-instances. New updated instances will be started automatically after that.
For the Imaging Service, the imaging worker needs to be terminated and started again:
# esi-manage-stack -a delete imaging
# esi-manage-stack -a create imaging

Here are the details from the Slackware 14.1 ChangeLog: +--------------------------+ patches/packages/glibc-2.17-i486-11_slack14.1.txz: Rebuilt. However, due to a patch applied to Slackware's glibc back in 2009 (don't use the gethostbyname4() lookup method as it was causing some cheap routers to misbehave), we were not vulnerable to that issue. Nevertheless it seems prudent to patch the overflows anyway even if we're not currently using the code in question. Thanks to mancha for the backported patch. For more information, see: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-7547 ( Security fix ) patches/packages/glibc-i18n-2.17-i486-11_slack14.1.txz: Rebuilt. patches/packages/glibc-profile-2.17-i486-11_slack14.1.txz: Rebuilt. patches/packages/glibc-solibs-2.17-i486-11_slack14.1.txz: Rebuilt. +--------------------------+

Vendor description:
"Securely connecting your small business to the outside world is as important as connecting your internal network devices to one another. Cisco Small Business RV Series Routers offer virtual private networking (VPN) technology so your remote workers can connect to your network through a secure Internet pathway."
Source: https://www.cisco.com/c/en/us/products/routers/small-business-rv-series-routers/index.html
Business recommendation:
We want to thank Cisco for the very quick and professional response and great coordination. Customers are urged to update the firmware of their devices.
Vulnerability overview/description:
1) Hardcoded Credentials The device contains hardcoded users and passwords which can be used to login via SSH on an emulated device at least.
During the communication with Cisco it turned out that: "Accounts like the 'debug-admin' and 'root' can not be accessed from console port, CLI or webui". Therefore, these accounts had no real functionality and cannot be used for malicious actions.
2) Known GNU glibc Vulnerabilities The used GNU glibc in version 2.19 is outdated and contains multiple known vulnerabilities. The outdated version was found by IoT Inspector.
3) Known BusyBox Vulnerabilities The used BusyBox toolkit in version 1.23.2 is outdated and contains multiple known vulnerabilities. The outdated version was found by IoT Inspector. One of the discovered vulnerabilities (CVE-2017-16544) was verified by using the MEDUSA scaleable firmware runtime.
4) Multiple Vulnerabilities - IoT Inspector Report Further information can be found in IoT Inspector report: https://r.sec-consult.com/ciscoiot
Proof of concept:
1) Hardcoded Credentials The following hardcoded hashes were found in the 'shadow' file of the firmware: root:$1$hPNSjUZA$7eKqEpqVYltt9xJ6f0OGf0:15533:0:99999:7::: debug-admin:$1$.AAm0iJ4$na9wZwly9pSrdS8MhcGKw/:15541:0:99999:7::: [...]
The undocumented user 'debug-admin' is also contained in this file.
Starting the dropbear daemon as background process on emulated firmware:
dropbear -E
[1109] Running in background
[1112] Child connection from :52718
[1112]
Log on via another host connected to the same network. For this PoC the password of the debug-admin was changed in the 'shadow' file.
[root@localhost medusa]# ssh debug-admin@
BusyBox v1.23.2 (2018-11-21 18:22:56 IST) built-in shell (ash)
/tmp $
The 'debug-admin' user has the same privileges like 'root'. This can be determined from the corresponding sudoers file in the firmware: [...]
User privilege specification
root ALL=(ALL) ALL debug-admin ALL=(ALL) ALL
Uncomment to allow members of group wheel to execute any command
%wheel ALL=(ALL) ALL
[...]
During the communication with Cisco it turned out that: "Accounts like the 'debug-admin' and 'root' can not be accessed from console port, CLI or webui". Therefore, these accounts had no real functionality and cannot be used for malicious actions.
2) Known GNU glibc Vulnerabilities GNU glibc version 2.19 contains multiple CVEs like: CVE-2014-4043, CVE-2014-9402, CVE-2014-9761, CVE-2014-9984, CVE-2015-1472, CVE-2015-5277, CVE-2015-8778, CVE-2015-8779, CVE-2017-1000366 and more.

.
The first vulnerability listed below is considered to have critical impact.
CVE-2015-7547
The Google Security Team and Red Hat discovered that the glibc
host name resolver function, getaddrinfo, when processing
AF_UNSPEC queries (for dual A/AAAA lookups), could mismanage its
internal buffers, leading to a stack-based buffer overflow and
arbitrary code execution. This vulnerability affects most
applications which perform host name resolution using getaddrinfo,
including system services.
CVE-2015-8776
Adam Nielsen discovered that if an invalid separated time value
is passed to strftime, the strftime function could crash or leak
information. Applications normally pass only valid time
information to strftime; no affected applications are known.
CVE-2015-8778
Szabolcs Nagy reported that the rarely-used hcreate and hcreate_r
functions did not check the size argument properly, leading to a
crash (denial of service) for certain arguments. No impacted
applications are known at this time.
CVE-2015-8779
The catopen function contains several unbound stack allocations
(stack overflows), causing it the crash the process (denial of
service). No applications where this issue has a security impact
are currently known.
While it is only necessary to ensure that all processes are not using the old glibc anymore, it is recommended to reboot the machines after applying the security upgrade.
For the stable distribution (jessie), these problems have been fixed in version 2.19-18+deb8u3.
For the unstable distribution (sid), these problems will be fixed in version 2.21-8

"Multiple stack-based buffer overflows in the (1) send_dg and (2) send_vc functions in the libresolv library in the GNU C Library (aka glibc or libc6) before 2.23 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted DNS response that triggers a call to the getaddrinfo function with the AF_UNSPEC or AF_INET6 address family, related to performing \"dual A/AAAA DNS queries\" and the libnss_dns.so.2 NSS module. GNU glibc is an open source C language compiler released under the LGPL license agreement. It is an implementation of the C library in the Linux operating system. \n\nThere is a stack overflow vulnerability in the getaddrinfo function in glibc when processing a specific DNS response packet. An attacker can use the vulnerability to launch an attack on a Linux host or related devices by constructing a malicious DNS service or using a man-in-the-middle attack, which results in remote code execution and can be obtained. User terminal control. \n\nThis update also fixes the following bugs:\n\n* The dynamic loader has been enhanced to allow the loading of more shared\nlibraries that make use of static thread local storage. While static thread\nlocal storage is the fastest access mechanism it may also prevent the\nshared library from being loaded at all since the static storage space is a\nlimited and shared process-global resource. Applications which would\npreviously fail with \"dlopen: cannot load any more object with static TLS\"\nshould now start up correctly. (BZ#1291270)\n\n* A bug in the POSIX realtime support would cause asynchronous I/O or\ncertain timer API calls to fail and return errors in the presence of large\nthread-local storage data that exceeded PTHREAD_STACK_MIN in size\n(generally 16 KiB). The bug in librt has been corrected and the impacted\nAPIs no longer return errors when large thread-local storage data is\npresent in the application. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\nNote: the current version of the following document is available here:\nhttps://h20564.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_n\na-c04989404\n\nSUPPORT COMMUNICATION - SECURITY BULLETIN\n\nDocument ID: c04989404\nVersion: 3\n\nHPSBGN03547 rev.3 - HPE Helion Eucalyptus Node Controller and other Helion\nEucalyptus Components using glibc, Remote Arbitrary Code Execution\n\nNOTICE: The information in this Security Bulletin should be acted upon as\nsoon as possible. \n\nRelease Date: 2016-02-18\nLast Updated: 2016-04-29\n\nPotential Security Impact: Remote Arbitrary Code Execution, Denial of Service\n(DoS)\n\nSource: Hewlett Packard Enterprise, Product Security Response Team\n\nVULNERABILITY SUMMARY\nA security vulnerability in glibc has been addressed with HPE Helion\nEucalyptus Node Controller and other Helion Eucalyptus components. The\nvulnerability could be exploited remotely resulting in arbitrary execution of\ncode. \n\n - Helion Eucalyptus Node Controller (NC) components are confirmed to be\naffected by the vulnerability. Other Helion Eucalyptus components and\npre-bundled service EMIs do not directly expose the vulnerability, but\nbecause glibc is a commonly used library on Linux, the exact exposure is hard\nto determine. Any software performing domain name resolution is potentially\nvulnerable. \n\nReferences:\n\n - CVE-2015-7547\n - PSRT110035\n\nSUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed. \n\n - HPE Helion Eucalyptus Node Controller 4.2.2 and earlier\n - HPE Helion Eucalyptus Service components EMIs for Load Balancing and\nImaging services package \"eucalyptus-service-image-1.48-0.87.99\" and earlier\n\nBACKGROUND\n\nCVSS 2.0 Base Metrics\n===========================================================\n Reference Base Vector Base Score\nCVE-2015-7547 (AV:N/AC:M/Au:N/C:P/I:P/A:P) 6.8\n===========================================================\n Information on CVSS is documented\n in HP Customer Notice: HPSN-2008-002\n\nRESOLUTION\n\nHPE has made the following software updates and workaround information\navailable to resolve the vulnerability with glibc for HPE Helion Eucalyptus. \n\n+ All hosts running HPE Helion Eucalyptus services should be upgraded to the\nlatest glibc. Updated glibc packages are available for RHEL and CentOS:\n\n https://access.redhat.com/articles/2161461\n\n **RHEL Note:** After following the guidelines for RHEL, a reboot is the\nsafest and recommended way to ensure that updates takes effect for all\nservices. \n\n**Workaround:**\n\n As a cloud administrator:\n\n 1) create an update-glibc script with the following content:\n\n #! /bin/bash\n yum update -y glibc\n\n 2) set the following cloud properties to use that script on instance start:\n\n euctl services.imaging.worker.init_script=@update-glibc\n euctl services.loadbalancing.worker.init_script=@update-glibc\n\n This script will be automatically executed for each of the new instances\nstarted from the service image. For instances that are already\nrunning, the cloud administrator will need to terminate them and start again\nfor the script to take effect. More specifically, for the Load Balancing\nservice, the cloud admin needs to find all instances running under the\n\"(eucalyptus)loadbalancing\" account:\n\n # euare-accountlist | grep loadbalancing\n (eucalyptus)loadbalancing \u003caccnt_id\u003e\n\n # euca-describe-instances verbose | grep \u003caccnt_id\u003e\n\n And terminate them using euca-terminate-instances. New updated instances\nwill be started automatically after that. \n\n For the Imaging Service, the imaging worker needs to be terminated and\nstarted again:\n\n # esi-manage-stack -a delete imaging\n # esi-manage-stack -a create imaging\n\nHISTORY\nVersion:1 (rev.1) - 17 February 2016 Initial release Version:2 (rev.2) - 28\nApril 2016 Update Helion Eucalyptus Service EMI\neucalyptus-service-image-1.57-0.93.110.el6 now available\nVersion:2 (rev.2) - 28 April 2016 Update Helion Eucalyptus Service EMI\neucalyptus-service-image-1.57-0.93.110.el6 now available\nVersion:3 (rev.3) - 29 April 2016 Changed impacted version from 4.2.1 to\n4.2.2 and earlier\n\nThird Party Security Patches: Third party security patches that are to be\ninstalled on systems running Hewlett Packard Enterprise (HPE) software\nproducts should be applied in accordance with the customer\u0027s patch management\npolicy. \n\nSupport: For issues about implementing the recommendations of this Security\nBulletin, contact normal HPE Services support channel.

However,\n due to a patch applied to Slackware\u0027s glibc back in 2009 (don\u0027t use the\n gethostbyname4() lookup method as it was causing some cheap routers to\n misbehave), we were not vulnerable to that issue. Nevertheless it seems\n prudent to patch the overflows anyway even if we\u0027re not currently using\n the code in question. Thanks to mancha for the backported patch. \n For more information, see:\n http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-7547\n (* Security fix *)\npatches/packages/glibc-i18n-2.17-i486-11_slack14.1.txz: Rebuilt. \npatches/packages/glibc-profile-2.17-i486-11_slack14.1.txz: Rebuilt. \npatches/packages/glibc-solibs-2.17-i486-11_slack14.1.txz: Rebuilt. \n+--------------------------+\n\n\nWhere to find the new packages:\n+-----------------------------+\n\nThanks to the friendly folks at the OSU Open Source Lab\n(http://osuosl.org) for donating FTP and rsync hosting\nto the Slackware project! :-)\n\nAlso see the \"Get Slack\" section on http://slackware.com for\nadditional mirror sites near you. \n\nUpdated packages for Slackware 14.1:\nftp://ftp.slackware.com/pub/slackware/slackware-14.1/patches/packages/glibc-2.17-i486-11_slack14.1.txz\nftp://ftp.slackware.com/pub/slackware/slackware-14.1/patches/packages/glibc-i18n-2.17-i486-11_slack14.1.txz\nftp://ftp.slackware.com/pub/slackware/slackware-14.1/patches/packages/glibc-profile-2.17-i486-11_slack14.1.txz\nftp://ftp.slackware.com/pub/slackware/slackware-14.1/patches/packages/glibc-solibs-2.17-i486-11_slack14.1.txz\n\nUpdated packages for Slackware x86_64 14.1:\nftp://ftp.slackware.com/pub/slackware/slackware64-14.1/patches/packages/glibc-2.17-x86_64-11_slack14.1.txz\nftp://ftp.slackware.com/pub/slackware/slackware64-14.1/patches/packages/glibc-i18n-2.17-x86_64-11_slack14.1.txz\nftp://ftp.slackware.com/pub/slackware/slackware64-14.1/patches/packages/glibc-profile-2.17-x86_64-11_slack14.1.txz\nftp://ftp.slackware.com/pub/slackware/slackware64-14.1/patches/packages/glibc-solibs-2.17-x86_64-11_slack14.1.txz\n\nUpdated packages for Slackware -current:\nftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/a/glibc-solibs-2.23-i586-1.txz\nftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/l/glibc-2.23-i586-1.txz\nftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/l/glibc-i18n-2.23-i586-1.txz\nftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/l/glibc-profile-2.23-i586-1.txz\n\nUpdated packages for Slackware x86_64 -current:\nftp://ftp.slackware.com/pub/slackware/slackware64-current/slackware64/a/glibc-solibs-2.23-x86_64-1.txz\nftp://ftp.slackware.com/pub/slackware/slackware64-current/slackware64/l/glibc-2.23-x86_64-1.txz\nftp://ftp.slackware.com/pub/slackware/slackware64-current/slackware64/l/glibc-i18n-2.23-x86_64-1.txz\nftp://ftp.slackware.com/pub/slackware/slackware64-current/slackware64/l/glibc-profile-2.23-x86_64-1.txz\n\n\nMD5 signatures:\n+-------------+\n\nSlackware 14.1 packages:\n4c56432d638adc8098661cfa818b5bc9 glibc-2.17-i486-11_slack14.1.txz\n5c316d6b0a8970fe15fbdf2adff8de19 glibc-i18n-2.17-i486-11_slack14.1.txz\na937d842e5ca3d0b125230c23285f8f4 glibc-profile-2.17-i486-11_slack14.1.txz\n442f01d094d350612c1fb1fcb5e7fbe7 glibc-solibs-2.17-i486-11_slack14.1.txz\n\nSlackware x86_64 14.1 packages:\neec88d584a79909ec79aae1c43c330d3 glibc-2.17-x86_64-11_slack14.1.txz\nd8b396eb6ada65d1555e3cf0fb8246c2 glibc-i18n-2.17-x86_64-11_slack14.1.txz\ne7deaabfe3e467cbde10ba5b7748bbbb glibc-profile-2.17-x86_64-11_slack14.1.txz\n629c93f0e510d354ff66e61f1ebe8b67 glibc-solibs-2.17-x86_64-11_slack14.1.txz\n\nSlackware -current packages:\nb11873e4f851a600b57a2e7a2ac8f472 a/glibc-solibs-2.23-i586-1.txz\n5116eec63fab5e7dbc58d27fecd48684 l/glibc-2.23-i586-1.txz\nae9b8a8e4ead59aa398212d6893d7ddc l/glibc-i18n-2.23-i586-1.txz\n61154e43ee4c0739dd5d3c4ce3b60ae6 l/glibc-profile-2.23-i586-1.txz\n\nSlackware x86_64 -current packages:\nc48a55c8a39dc8e17e04796e4f160bd0 a/glibc-solibs-2.23-x86_64-1.txz\n36104e1a004b0e97d193c2132f18222d l/glibc-2.23-x86_64-1.txz\ne0415f66d17323c8f6df339cfd49051b l/glibc-i18n-2.23-x86_64-1.txz\nf5433793e9da696a60f2445559f1d33f l/glibc-profile-2.23-x86_64-1.txz\n\n\nInstallation instructions:\n+------------------------+\n\nUpgrade the packages as root:\n# upgradepkg glibc-*.txz\n\n\n+-----+\n\nSlackware Linux Security Team\nhttp://slackware.com/gpg-key\nsecurity@slackware.com\n\n+------------------------------------------------------------------------+\n| To leave the slackware-security mailing list: |\n+------------------------------------------------------------------------+\n| Send an email to majordomo@slackware.com with this text in the body of |\n| the email message: |\n| |\n| unsubscribe slackware-security |\n| |\n| You will get a confirmation message back containing instructions to |\n| complete the process.

Weber / @2019\n\n. \n\nThe first vulnerability listed below is considered to have critical\nimpact. \n\nCVE-2015-7547\n\n The Google Security Team and Red Hat discovered that the glibc\n host name resolver function, getaddrinfo, when processing\n AF_UNSPEC queries (for dual A/AAAA lookups), could mismanage its\n internal buffers, leading to a stack-based buffer overflow and\n arbitrary code execution. This vulnerability affects most\n applications which perform host name resolution using getaddrinfo,\n including system services. \n\nCVE-2015-8776\n\n Adam Nielsen discovered that if an invalid separated time value\n is passed to strftime, the strftime function could crash or leak\n information. Applications normally pass only valid time\n information to strftime; no affected applications are known. \n\nCVE-2015-8778\n\n Szabolcs Nagy reported that the rarely-used hcreate and hcreate_r\n functions did not check the size argument properly, leading to a\n crash (denial of service) for certain arguments. No impacted\n applications are known at this time. \n\nCVE-2015-8779\n\n The catopen function contains several unbound stack allocations\n (stack overflows), causing it the crash the process (denial of\n service). No applications where this issue has a security impact\n are currently known. \n\nWhile it is only necessary to ensure that all processes are not using\nthe old glibc anymore, it is recommended to reboot the machines after\napplying the security upgrade. \n\nFor the stable distribution (jessie), these problems have been fixed in\nversion 2.19-18+deb8u3. \n\nFor the unstable distribution (sid), these problems will be fixed in\nversion 2.21-8", "sources": [ { "db": "NVD", "id": "CVE-2015-7547" }, { "db": "CNVD", "id": "CNVD-2016-01100" }, { "db": "VULHUB", "id": "VHN-85508" }, { "db":
