Synopsis
A vulnerability was found in libxslt, possibly resulting in the execution of arbitrary code and Denial of Service.
Background
Libxslt is the XSLT C library developed for the GNOME project. XSLT itself is an XML language to define transformations for XML.
Affected packages
Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/libxslt < 1.1.24 >= 1.1.24
Description
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()".
Impact
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.
Workaround
There is no known workaround at this time.
Resolution
All libxslt users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libxslt-1.1.24"
