critical Nessus Plugin ID 90336

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Mitre reports :

The pcre_compile2 function in pcre_compile.c in PCRE 8.38 mishandles a specific pattern and related patterns with named subgroups, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possible have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.

Solution

Update the affected package.
