|Gentoo Linux Security Advisory
Title: libxslt: Execution of arbitrary code (GLSA 200806-02)
Date: June 03, 2008
A vulnerability was found in libxslt, possibly resulting in the execution of arbitrary code and Denial of Service.
Libxslt is the XSLT C library developed for the GNOME project. XSLT itself is an XML language to define transformations for XML.
Vulnerable: < 1.1.24
Unaffected: >= 1.1.24
Architectures: All supported architectures
Anthony de Almeida Lopes reported a vulnerability in libxslt when handling XSL style-sheet files, which could be exploited to trigger the use of uninitialized memory, e.g. in a call to "free()".
A remote attacker could entice a user or automated system to process an XML file using a specially crafted XSL transformation file, possibly resulting in the execution of arbitrary code or a Denial of Service.
There is no known workaround at this time.
All libxslt users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libxslt-1.1.24"
