The remote Red Hat host is missing one or more security updates.
Updated glibc packages that fix multiple security issues and one bug
are now available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.
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.
