Detail
Problem 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1064066 - Test suite failure: test-ldouble 1098042 - getaddrinfo return EAI_NONAME instead of EAI_AGAIN in case the DNS query times out 1144133 - calloc in dl-reloc.c computes size incorrectly 1187109 - CVE-2013-7423 glibc: getaddrinfo() writes DNS queries to random file descriptors under high load 1188235 - CVE-2015-1472 glibc: heap buffer overflow in glibc swscanf 1195762 - glibc: _IO_wstr_overflow integer overflow 1197730 - glibc: potential denial of service in internal_fnmatch() 1199525 - CVE-2015-1781 glibc: buffer overflow in gethostbyname_r() and related functions with misaligned buffer 1207032 - glibc deadlock when printing backtrace from memory allocator 1209105 - CVE-2015-1473 glibc: Stack-overflow in glibc swscanf 1219891 - Missing define for TCP_USER_TIMEOUT in netinet/tcp.h 1225490 - [RFE] Unconditionally enable SDT probes in glibc builds. |
