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"
