Scientific Linux Security Update : glibc on SL5.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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.

All users of glibc are advised to upgrade to these updated packages,
which contain backported patches to correct these issues.
