A vulnerability was found in libxslt, possibly resulting in the execution of arbitrary code and Denial of Service.

Affected packages

Background

Libxslt is the XSLT C library developed for the GNOME project. XSLT itself is an XML language to define transformations for XML.

Description

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.

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-libs/libxslt-1.1.24"
