Detailsinfo

A vulnerability has been found in PCRE 6.9 (Programming Tool Software) and classified as problematic. Affected by this vulnerability is an unknown part. The manipulation with an unknown input leads to a numeric error vulnerability. The CWE definition for the vulnerability is CWE-189. As an impact it is known to affect availability. The summary by CVE is:

Perl-Compatible Regular Expression (PCRE) library before 7.0 does not properly calculate the amount of memory needed for a compiled regular expression pattern when the (1) -x or (2) -i UTF-8 options change within the pattern, which allows context-dependent attackers to cause a denial of service (PCRE or glibc crash) via crafted regular expressions.

The bug was discovered 12/19/2006. The weakness was released 11/15/2007 as Bug 384801 as not defined bug report (Bugzilla). The advisory is shared at bugzilla.redhat.com. This vulnerability is known as CVE-2006-7230 since 11/15/2007. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 331 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 29549 (SuSE 10 Security Update : pcre (ZYPP Patch Number 4748)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165666 (SUSE Enterprise Linux Security Update php4, php5 (SUSE-SA:2008:004)).

Upgrading to version 6.9 eliminates this vulnerability. A possible mitigation has been published 2 weeks after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (38582), Tenable (29549), SecurityFocus (BID 26550†), OSVDB (40758†) and Secunia (SA27741†).
