Categoría:	CentOS Local Security Checks
Título:	CentOS Update for glibc CESA-2012:0393 centos6
Resumen:	The remote host is missing an update for the 'glibc'; package(s) announced via the referenced advisory.
Descripción:	Summary: The remote host is missing an update for the 'glibc' package(s) announced via the referenced advisory. Vulnerability Insight: The glibc packages provide the standard C and standard math libraries used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. An integer overflow flaw was found in the implementation of the printf functions family. This could allow an attacker to bypass FORTIFY_SOURCE protections and execute arbitrary code using a format string flaw in an application, even though these protections are expected to limit the impact of such flaws to an application abort. (CVE-2012-0864) This update also fixes the following bugs: * Previously, the dynamic loader generated an incorrect ordering for initialization according to the ELF specification. This could result in incorrect ordering of DSO constructors and destructors. With this update, dependency resolution has been fixed. (BZ#783999) * Previously, locking of the main malloc arena was incorrect in the retry path. This could result in a deadlock if an sbrk request failed. With this update, locking of the main arena in the retry path has been fixed. This issue was exposed by a bug fix provided in the RHSA-2012:0058 update. (BZ#795328) * Calling memcpy with overlapping arguments on certain processors would generate unexpected results. While such code is a clear violation of ANSI/ISO standards, this update restores prior memcpy behavior. (BZ#799259) All users of glibc are advised to upgrade to these updated packages, which contain patches to resolve these issues. Affected Software/OS: glibc on CentOS 6 Solution: Please install the updated packages. CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
