SECUNIA ADVISORY ID:
SA30315

VERIFY ADVISORY:
http://secunia.com/advisories/30315/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
libxslt 1.x
http://secunia.com/product/18744/

DESCRIPTION:
A vulnerability has been reported in libxslt, which can be exploited
by malicious people to cause a DoS (Denial of Service) and
potentially to compromise a vulnerable system.

The vulnerability is caused due to an error in the handling of XSL
style-sheet files. This can potentially be exploited to trigger the
use of uninitialized memory in e.g. a call to "free()" when a
specially crafted XSL file is being processed by an application using
the library.

Successful exploitation may allow execution of arbitrary code.

SOLUTION:
Reportedly fixed in version 1.1.24.
