Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
A vulnerability was found in libxslt, possibly resulting in the
execution of arbitrary code and Denial of Service.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Libxslt is the XSLT C library developed for the GNOME project. XSLT
itself is an XML language to define transformations for XML.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-libs/libxslt < 1.1.24 >=3D 1.1.24
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
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
=3D=3D=3D=3D=3D=3D
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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All libxslt users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Ddev-libs/libxslt-1.1.24"
