Package : libzip
Date : March 23, 2012
Affected: 2010.1, 2011., Enterprise Server 5.0
_______________________________________________________________________
Problem Description:
Multiple vulnerabilities has been found and corrected in libzip:
libzip (version <= 0.10) uses an incorrect loop construct, which can
result in a heap overflow on corrupted zip files (CVE-2012-1162).
libzip (version <= 0.10) has a numeric overflow condition, which,
for example, results in improper restrictions of operations within
the bounds of a memory buffer (e.g., allowing information leaks)
(CVE-2012-1163).
The updated packages have been upgraded to the 0.10.1 version to
correct these issues.
