A vulnerability in libxslt could result in Denial of Service.

2.  Impact Information


libxslt is the XSLT C library developed for the GNOME project. XSLT is an XML language to define transformations for XML.


An out of bounds read error has been found in libxslt/pattern.c in libxslt.


A remote attacker could entice a user to process an XML file using a specially crafted XSLT stylesheet in an application linked against libxslt, possibly resulting in a Denial of Service condition.

3.  Resolution Information


There is no known workaround at this time.


All libxslt users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-libs/libxslt-1.1.26-r3"
