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.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/libzip < 0.10.1 >= 0.10.1
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"
