Synopsis
Multiple vulnerabilities have been found in libzip, the worst of
which might allow execution of arbitrary code.
2.
Impact Information
Background
libzip is a library for manipulating zip archives.
Description
Two vulnerabilities have been found in the "_zip_readcdir()" function in
zip_open.c of libzip:
- An incorrect loop construct, which could cause a heap-based buffer
overflow (CVE-2012-1162).
- An integer overflow, which may not restrict operations within the
memory buffer (CVE-2012-1163).
Impact
A remote attacker could entice a user to open a specially crafted ZIP
file, possibly resulting in execution of arbitrary code with the
privileges of the process, a Denial of Service condition, or information
leaks.

Resolution Information
Workaround
