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"
