ID CVE-2015-1781
Summary Buffer overflow in the gethostbyname_r and other unspecified NSS functions in the GNU C Library (aka glibc or libc6) before 2.22 allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DNS response, which triggers a call with a misaligned buffer.

CWE CWE-119
CAPEC
  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.
  • Overflow Binary Resource File
    An attack of this type exploits a buffer overflow vulnerability in the handling of binary resources. Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the attacker access to the execution stack and execute arbitrary code in the target process. This attack pattern is a variant of standard buffer overflow attacks using an unexpected vector (binary files) to wrap its attack and open up a new attack vector. The attacker is required to either directly serve the binary content to the victim, or place it in a locale like a MP3 sharing application, for the victim to download. The attacker then is notified upon the download or otherwise locates the vulnerability opened up by the buffer overflow.
  • Buffer Overflow via Symbolic Links
    This type of attack leverages the use of symbolic links to cause buffer overflows. An attacker can try to create or manipulate a symbolic link file such that its contents result in out of bounds data. When the target software processes the symbolic link file, it could potentially overflow internal buffers with insufficient bounds checking.
  • Overflow Variables and Tags
    This type of attack leverages the use of tags or variables from a formatted configuration data to cause buffer overflow. The attacker crafts a malicious HTML page or configuration file that includes oversized strings, thus causing an overflow.
  • Buffer Overflow via Parameter Expansion
    In this attack, the target software is given input that the attacker knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.
  • Buffer Overflow in an API Call
    This attack targets libraries or shared code modules which are vulnerable to buffer overflow attacks. An attacker who has access to an API may try to embed malicious code in the API function call and exploit a buffer overflow vulnerability in the function's implementation. All clients that make use of the code library thus become vulnerable by association. This has a very broad effect on security across a system, usually affecting more than one software process.
  • Buffer Overflow in Local Command-Line Utilities
    This attack targets command-line utilities available in a number of shells. An attacker can leverage a vulnerability found in a command-line utility to escalate privilege to root.

    description The remote host is affected by the vulnerability described in GLSA-201602-02 (GNU C Library: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in the GNU C Library: The Google Security Team and Red Hat discovered a stack-based buffer overflow in the send_dg() and send_vc() functions due to a buffer mismanagement when getaddrinfo() is called with AF_UNSPEC (CVE-2015-7547). The strftime() function access invalid memory when passed out-of-range data, resulting in a crash (CVE-2015-8776). An integer overflow was found in the __hcreate_r() function (CVE-2015-8778). Multiple unbounded stack allocations were found in the catopen() function (CVE-2015-8779). Please review the CVEs referenced below for additional vulnerabilities that had already been fixed in previous versions of sys-libs/glibc, for which we have not issued a GLSA before. Impact : A remote attacker could exploit any application which performs host name resolution using getaddrinfo() in order to execute arbitrary code or crash the application. The other vulnerabilities can possibly be exploited to cause a Denial of Service or leak information. Workaround : A number of mitigating factors for CVE-2015-7547 have been identified. Please review the upstream advisory and references below.

    description Several vulnerabilities have been fixed in the GNU C Library, eglibc. The CVE-2015-7547 vulnerability listed below is considered to have critical impact. - CVE-2014-8121 Robin Hack discovered that the nss_files database did not correctly implement enumeration interleaved with name-based or ID-based lookups. This could cause the enumeration enter an endless loop, leading to a denial of service. - CVE-2015-1781 Arjun Shankar discovered that the _r variants of host name resolution functions (like gethostbyname_r), when performing DNS name resolution, suffered from a buffer overflow if a misaligned buffer was supplied by the applications, leading to a crash or, potentially, arbitrary code execution. Most applications are not affected by this vulnerability because they use aligned buffers. - CVE-2015-7547 The Google Security Team and Red Hat discovered that the eglibc 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-2015-8777 Hector Marco-Gisbert reported that LD_POINTER_GUARD was not ignored for SUID programs, enabling an unintended bypass of a security feature. This update causes eglibc to always ignore the LD_POINTER_GUARD environment variable. - 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. The following fixed vulnerabilities currently lack CVE assignment : - Joseph Myers reported that an integer overflow in the strxfrm can lead to heap-based buffer overflow, possibly allowing arbitrary code execution. In addition, a fallback path in strxfrm uses an unbounded stack allocation (stack overflow), leading to a crash or erroneous application behavior. - Kostya Serebryany reported that the fnmatch function could skip over the terminating NUL character of a malformed pattern, causing an application calling fnmatch to crash (denial of service). - Joseph Myers reported that the IO_wstr_overflow function, internally used by wide-oriented character streams, suffered from an integer overflow, leading to a heap-based buffer overflow. On GNU/Linux systems, wide-oriented character streams are rarely used, and no affected applications are known. - Andreas Schwab reported a memory leak (memory allocation without a matching deallocation) while processing certain DNS answers in getaddrinfo, related to the _nss_dns_gethostbyname4_r function. This vulnerability could lead to a denial of service. While it is only necessary to ensure that all processes are not using the old eglibc anymore, it is recommended to reboot the machines after applying the security upgrade.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. It was discovered that the nss_files backend for the Name Service Switch in glibc would return incorrect data to applications or corrupt the heap (depending on adjacent heap contents).

  • NASL family CentOS Local Security Checks
    NASL id CENTOS_RHSA-2015-2199.NASL
    description Updated glibc packages that fix multiple security issues, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. It was discovered that, under certain circumstances, glibc's getaddrinfo() function would send DNS queries to random file descriptors. An attacker could potentially use this flaw to send DNS queries to unintended recipients, resulting in information disclosure or data loss due to the application encountering corrupted data. (CVE-2013-7423) A buffer overflow flaw was found in the way glibc's gethostbyname_r() and other related functions computed the size of a buffer when passed a misaligned buffer as input. An attacker able to make an application call any of these functions with a misaligned buffer could use this flaw to crash the application or, potentially, execute arbitrary code with the permissions of the user running the application. (CVE-2015-1781) A heap-based buffer overflow flaw and a stack overflow flaw were found in glibc's swscanf() function. An attacker able to make an application call the swscanf() function could use these flaws to crash that application or, potentially, execute arbitrary code with the permissions of the user running the application. (CVE-2015-1472, CVE-2015-1473) An integer overflow flaw, leading to a heap-based buffer overflow, was found in glibc's _IO_wstr_overflow() function. An attacker able to make an application call this function could use this flaw to crash that application or, potentially, execute arbitrary code with the permissions of the user running the application. (BZ#1195762) A flaw was found in the way glibc's fnmatch() function processed certain malformed patterns. An attacker able to make an application call this function could use this flaw to crash that application. (BZ#1197730) The CVE-2015-1781 issue was discovered by Arjun Shankar of Red Hat. These updated glibc packages also include numerous bug fixes and one enhancement. Space precludes documenting all of these changes in this advisory. For information on the most significant of these changes, users are directed to the following article on the Red Hat Customer Portal : https://access.redhat.com/articles/2050743 All glibc users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements.

    description Arjun Shankar of Red Hat discovered that gethostbyname_r and related functions compute the size of an input buffer incorrectly if the passed-in buffer is misaligned. This results in a buffer overflow. For the oldoldstable distribution (squeeze), this problem has been fixed in version 2.11.3-4+deb6u6.
