libxslt XSL buffer overflow

libxslt-xsl-bo (42560) The risk level is classified as HighHigh Risk

Description:

libxslt is vulnerable to a buffer overflow, caused by improper bounds checking during XML document transformation. By using a specially-crafted XSL style-sheet file, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the XSLT processor to crash.
