USN-173-2: PCRE vulnerability

Publication date

Overview

PCRE vulnerability

Releases


Details

USN-173-1 fixed a buffer overflow vulnerability in the PCRE library.
However, it was determined that this did not suffice to prevent all
possible overflows, so another update is necessary.

In addition, it was found that the Ubuntu 4.10 version of Apache 2
contains a static copy of the library code, so this package needs to
be updated as well. In Ubuntu 5.04, Apache 2 uses the external library
from the libpcre3 package.
