libxslt: Execution of arbitrary code
Gentoo Linux Security Advisory

All supported architectures
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.
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:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libxslt-1.1.24"
