17
18 A vulnerability in libxslt could result in Denial of Service.
19
20 Background

37 An out of bounds read error has been found in libxslt/pattern.c in
38 libxslt.
39
40 Impact
41 ======
42
43 A remote attacker could entice a user to process an XML file using a
44 specially crafted XSLT stylesheet in an application linked against
45 libxslt, possibly resulting in a Denial of Service condition.

50 There is no known workaround at this time.
51
52 Resolution
53 ==========
