CVE-2012-4412

Status Candidate

Overview

Integer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string, which triggers a heap-based buffer overflow.

Mandriva Linux Security Advisory 2013-284
Posted Nov 26, 2013

Mandriva Linux Security Advisory 2013-284 - Integer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service or possibly execute arbitrary code via a long string, which triggers a heap-based buffer overflow. Stack-based buffer overflow in string/strcoll_l.c in the GNU C Library 2.17 and earlier allows context-dependent attackers to cause a denial of service or possibly execute arbitrary code via a long string that triggers a malloc failure and use of the alloca function. Multiple integer overflows in malloc/malloc.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allow context-dependent attackers to cause a denial of service via a large value to the aligned_alloc functions. A stack overflow flaw, which led to a denial of service (application crash), was found in the way glibc's getaddrinfo() function processed certain requests when called with AF_INET6. A similar flaw to this affects AF_INET6 rather than AF_UNSPEC. The PTR_MANGLE implementation in the GNU C Library (aka glibc or libc6) 2.4, 2.17, and earlier, and Embedded GLIBC does not initialize the random value for the pointer guard, which makes it easier for context- dependent attackers to control execution flow by leveraging a buffer-overflow vulnerability in an application and using the known zero value pointer guard to calculate a pointer address. The updated packages have been patched to correct these issues.

Mandriva Linux Security Advisory 2013-283

Mandriva Linux Security Advisory 2013-283 - Updated glibc packages fix multiple security issues. Integer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service or possibly execute arbitrary code via a long string, which triggers a heap-based buffer overflow. Stack-based buffer overflow in string/strcoll_l.c in the GNU C Library 2.17 and earlier allows context-dependent attackers to cause a denial of service or possibly execute arbitrary code via a long string that triggers a malloc failure and use of the alloca function. pt_chown in GNU C Library before 2.18 does not properly check permissions for tty files, which allows local users to change the permission on the files and obtain access to arbitrary pseudo-terminals by leveraging a FUSE file system. Various other issues were also addressed.

Ubuntu Security Notice USN-1991-1
Posted Oct 21, 2013
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1991-1 - It was discovered that the GNU C Library incorrectly handled the strcoll() function. An attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. It was discovered that the GNU C Library incorrectly handled multibyte characters in the regular expression matcher. An attacker could use this issue to cause a denial of service. It was discovered that the GNU C Library incorrectly handled large numbers of domain conversion results in the getaddrinfo() function. An attacker could use this issue to cause a denial of service. Various other issues were also addressed.
