ID CVE-2011-1658
Summary ld.so in the GNU C Library (aka glibc or libc6) 2.13 and earlier expands the $ORIGIN dynamic string token when RPATH is composed entirely of this token, which might allow local users to gain privileges by creating a hard link in an arbitrary directory to a (1) setuid or (2) setgid program with this RPATH value, and then executing the program with a crafted value for the LD_PRELOAD environment variable, a different vulnerability than CVE-2010-3847 and CVE-2011-0536. NOTE: it is not expected that any standard operating-system distribution would ship an applicable setuid or setgid program.

Base: 3.7 (as of 08-04-2011 - 14:16)
Impact:
Exploitability:
CWE CWE-264
CAPEC
  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

The fix for CVE-2010-3847 introduced a regression in the way the dynamic loader expanded the $ORIGIN dynamic string token specified in the RPATH and RUNPATH entries in the ELF library header. A local attacker could use this flaw to escalate their privileges via a setuid or setgid program using such a library. (CVE-2011-0536) It was discovered that the glibc addmntent() function did not sanitize its input properly. A local attacker could possibly use this flaw to inject malformed lines into /etc/mtab via certain setuid mount helpers, if the attacker were allowed to mount to an arbitrary directory under their control. (CVE-2010-0296) It was discovered that the glibc fnmatch() function did not properly restrict the use of alloca(). If the function was called on sufficiently large inputs, it could cause an application using fnmatch() to crash or, possibly, execute arbitrary code with the privileges of the application. (CVE-2011-1071) It was discovered that the locale command did not produce properly escaped output as required by the POSIX specification. If an attacker were able to set the locale environment variables in the environment of a script that performed shell evaluation on the output of the locale command, and that script were run with different privileges than the attacker's, it could execute arbitrary code with the privileges of the script. (CVE-2011-1095) All users should upgrade to these updated packages, which contain backported patches to correct these issues.

(CVE-2011-1095) All users should upgrade to these updated packages, which contain backported patches to correct these issues.

    description The remote VMware ESXi 5.0 host is affected by the following security vulnerabilities : - A security bypass vulnerability exists in the e1000 driver in the Linux kernel due to improper handling of Ethernet frames that exceed the MTU. An unauthenticated, remote attacker can exploit this, via trailing payload data, to bypass packet filters. (CVE-2009-4536) - An error exists in the file misc/mntent_r.c that could allow a local attacker to cause denial of service conditions. (CVE-2010-0296) - An error exists related to glibc, the dynamic linker and '$ORIGIN' substitution that could allow privilege escalation. (CVE-2011-0536) - An error exists in the function 'fnmatch' in the file posix/fnmatch.c that could allow arbitrary code execution. (CVE-2011-1071) - An error exists in the file locale/programs/locale.c related to localization environment variables that could allow privilege escalation. (CVE-2011-1095) - An error exists related to glibc, the dynamic linker and 'RPATH' that could allow privilege escalation. (CVE-2011-1658) - An error exists in the function 'fnmatch' related to UTF-8 string handling that could allow privilege escalation. (CVE-2011-1659)

    description It was discovered that the GNU C Library did not properly handle integer overflows in the timezone handling code. An attacker could use this to possibly execute arbitrary code by convincing an application to load a maliciously constructed tzfile. (CVE-2009-5029) It was discovered that the GNU C Library did not properly handle passwd.adjunct.byname map entries in the Network Information Service (NIS) code in the name service caching daemon (nscd). An attacker could use this to obtain the encrypted passwords of NIS accounts. This issue only affected Ubuntu 8.04 LTS. (CVE-2010-0015) Chris Evans reported that the GNU C Library did not properly calculate the amount of memory to allocate in the fnmatch() code. An attacker could use this to cause a denial of service or possibly execute arbitrary code via a maliciously crafted UTF-8 string. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS and Ubuntu 10.10. (CVE-2011-1071) Tomas Hoger reported that an additional integer overflow was possible in the GNU C Library fnmatch() code. An attacker could use this to cause a denial of service via a maliciously crafted UTF-8 string. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-1659) Dan Rosenberg discovered that the addmntent() function in the GNU C Library did not report an error status for failed attempts to write to the /etc/mtab file. This could allow an attacker to corrupt /etc/mtab, possibly causing a denial of service or otherwise manipulate mount options. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-1089) Harald van Dijk discovered that the locale program included with the GNU C library did not properly quote its output. This could allow a local attacker to possibly execute arbitrary code using a crafted localization string that was evaluated in a shell script. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS and Ubuntu 10.10. (CVE-2011-1095) It was discovered that the GNU C library loader expanded the $ORIGIN dynamic string token when RPATH is composed entirely of this token. This could allow an attacker to gain privilege via a setuid program that had this RPATH value. (CVE-2011-1658) It was discovered that the GNU C library implementation of memcpy optimized for Supplemental Streaming SIMD Extensions 3 (SSSE3) contained a possible integer overflow. An attacker could use this to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 10.04 LTS. (CVE-2011-2702) John Zimmerman discovered that the Remote Procedure Call (RPC) implementation in the GNU C Library did not properly handle large numbers of connections. This could allow a remote attacker to cause a denial of service. (CVE-2011-4609) It was discovered that the GNU C Library vfprintf() implementation contained a possible integer overflow in the format string protection code offered by FORTIFY_SOURCE. An attacker could use this flaw in conjunction with a format string vulnerability to bypass the format string protection and possibly execute arbitrary code. (CVE-2012-0864). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    title Ubuntu 8.04 LTS / 10.04 LTS / 10.10 / 11.04 / 11.10 : eglibc, glibc vulnerabilities (USN-1396-1)
  • NASL family Oracle Linux Local Security Checks
    NASL id ORACLELINUX_ELSA-2011-0412.NASL
    description From Red Hat Security Advisory 2011:0412 : Updated glibc packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team 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 contain the standard C libraries used by multiple programs on the system. These packages contain the standard C and the standard math libraries. Without these two libraries, a Linux system cannot function properly. The fix for CVE-2010-3847 introduced a regression in the way the dynamic loader expanded the $ORIGIN dynamic string token specified in the RPATH and RUNPATH entries in the ELF library header. A local attacker could use this flaw to escalate their privileges via a setuid or setgid program using such a library. (CVE-2011-0536) It was discovered that the glibc addmntent() function did not sanitize its input properly. A local attacker could possibly use this flaw to inject malformed lines into /etc/mtab via certain setuid mount helpers, if the attacker were allowed to mount to an arbitrary directory under their control. (CVE-2010-0296) It was discovered that the glibc fnmatch() function did not properly restrict the use of alloca(). If the function was called on sufficiently large inputs, it could cause an application using fnmatch() to crash or, possibly, execute arbitrary code with the privileges of the application. (CVE-2011-1071) It was discovered that the locale command did not produce properly escaped output as required by the POSIX specification. If an attacker were able to set the locale environment variables in the environment of a script that performed shell evaluation on the output of the locale command, and that script were run with different privileges than the attacker's, it could execute arbitrary code with the privileges of the script. (CVE-2011-1095) All users should upgrade to these updated packages, which contain backported patches to correct these issues.
