Categoría:	CentOS Local Security Checks
Título:	CentOS Update for glibc CESA-2012:1207 centos5
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 properly. Multiple integer overflow flaws, leading to stack-based buffer overflows, were found in glibc's functions for converting a string to a numeric representation (strtod(), strtof(), and strtold()). If an application used such a function on attacker controlled input, it could cause the application to crash or, potentially, execute arbitrary code. (CVE-2012-3480) This update also fixes the following bug: * Previously, logic errors in various mathematical functions, including exp, exp2, expf, exp2f, pow, sin, tan, and rint, caused inconsistent results when the functions were used with the non-default rounding mode. This could also cause applications to crash in some cases. With this update, the functions now give correct results across the four different rounding modes. (BZ#839411) All users of glibc are advised to upgrade to these updated packages, which contain backported patches to correct these issues. Affected Software/OS: glibc on CentOS 5 Solution: Please install the updated packages. CVSS Score: 4.6 CVSS Vector: AV:L/AC:L/Au:N/C:P/I:P/A:P
