Detail

Synopsis

Multiple vulnerabilities have been found in libzip, the worst of which might allow execution of arbitrary code.

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.

Workaround

There is no known workaround at this time.

Resolution

All libzip users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libzip-0.10.1"
