Red Hat: 2012:1207-01: glibc: Moderate Advisory
Summary
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.
Summary
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
