Gentoo Linux Security Advisory
Title: libzip: Multiple vulnerabilities (GLSA 201203-23)
Severity: normal
Exploitable: remote
Date: March 29, 2012
Bug(s): #409117
ID: 201203-23
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: dev-libs/libzip
Vulnerable: < 0.10.1
Unaffected: >= 0.10.1
Architectures: All supported architectures
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: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libzip-0.10.1"
|
