(In reply to comment #1) > @security, please add it to existing glsa. Added and updated. Thank you. Side note for GLSA reviewers: both issues CVE MERGED to CVE-2012-6139 [1] [1] http://seclists.org/oss-sec/2013/q1/738
CVE-2012-6139 (http://nvd.nist.gov/nvd.cfm?cvename=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? :)
