"Tavis Ormandy of the Google Security Team discovered a heap-based
buffer overflow when compiling certain regular expression patterns.
This could be used by a malicious attacker by sending a specially
crafted regular expression to an application using the PCRE library,
resulting in the possible execution of arbitrary code or a denial of
service (CVE-2008-2371).

The updated packages have been patched to correct this issue."
