Description Martin Prpič 2015-03-30 08:24:08 EDT

A flaw was found in the PCRE library:

PCRE library is prone to a vulnerability which leads to Heap overflow. Without enough bound checking inside pcre_compile2(), the heap memory could be overflowed via a crafted regular expression. Since PCRE library is widely used, this vulnerability should affect many applications. An attacker may exploit this issue to execute arbitrary code in the context of the user running the affected application.

Upstream issue:

http://bugs.exim.org/show_bug.cgi?id=1592

Upstream patch:

http://vcs.pcre.org/pcre?revision=1529&view=revision

Statement:

This issue did not affect the versions of pcre as shipped with Red Hat Enterprise Linux 5, 6, and 7.
