Description

HP's Zero Day Initiative has identified a vulnerability affecting the pcre3 package. It was assigned ZDI id ZDI-CAN-3542. A CVE identifier has not been assigned yet.

PCRE Regular Expression Compilation Stack Buffer Overflow Remote Code Execution Vulnerability.

PCRE did not validate that handling the (*ACCEPT) verb will occur within the bounds of the cworkspace stack buffer, leading to a stack buffer overflow.

For Debian 6 'Squeeze', these problems have been fixed in version 8.02-1.1+deb6u1.

We recommend that you upgrade your pcre3 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
