The remote Scientific Linux host is missing one or more security
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.
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.
- 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 a
- 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.
All users of glibc are advised to upgrade to these updated packages,
which contain patches to resolve these issues.
