Gentoo Linux Security Advisory
Title: libxslt: Denial of Service (GLSA 201401-07)
Severity: normal
Exploitable: remote
Date: January 10, 2014
Bug(s): #433603, #436284, #463236, #496114
ID: 201401-07
Synopsis
Multiple Denial of Service vulnerabilities have been found in
libxslt.
Background
libxslt is the XSLT C library developed for the GNOME project. XSLT is
an XML language to define transformations for XML.
Affected Packages
Package: dev-libs/libxslt
Vulnerable: < 1.1.28
Unaffected: >= 1.1.28
Architectures: All supported architectures
Description
Multiple vulnerabilities have been found in libxslt: - Multiple errors exist in pattern.c and functions.c (CVE-2012-2870,
CVE-2012-6139).
- A double-free error exists in templates.c (CVE-2012-2893).
- A NULL pointer dereference in keys.c (CVE-2012-6139).
- An error in handling stylesheets containing DTDs (CVE-2013-4520).
Impact
A remote attacker could entice a user to process a specially crafted
file in an application linked against libxslt, possibly resulting in a
Denial of Service condition.
Workaround
There is no known workaround at this time.
Resolution
All libxslt users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libxslt-1.1.28"
| Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these packages.
