GLSA-200806-02 : libxslt: Execution of arbitrary code
High Nessus Plugin ID 33085
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200806-02 (libxslt: Execution of arbitrary code)
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.
SolutionAll libxslt users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/libxslt-1.1.24'
