Description Agostino Sarubbo gentoo-dev 2013-03-25 15:27:06 UTC
From ${URL} :

Two vulnerabilities have been reported in libxslt, which can be exploited by malicious people to cause a DoS (Denial of Service).

1) An error within the "xsltDocumentFunction()" function (libxslt/functions.c) when parsing XSL templates can be exploited to cause a crash.

2) A NULL-pointer dereference error within the "xsltAddKey()" function (libxslt/keys.c) when parsing XSL keys can be exploited to cause a crash.

The vulnerabilities are reported in versions prior to 1.1.28.

Update to version 1.1.28.

CVE-2012-6139 (
  libxslt before 1.1.28 allows remote attackers to cause a denial of service
  (NULL pointer dereference and crash) via an (1) empty match attribute in a
  XSL key to the xsltAddKey function in keys.c or (2) uninitialized variable
  to the xsltDocumentFunction function in functions.c.

We don't have <dev-libs/libxslt-1.1.28 in the tree any more since March 2013.

Maybe it's finally time to mark this bug as resolved? :)
