Description:
An integer overflow problem was discovered in the Perl Compatible
Regular Expressions (PCRE) [1] library, version 6.2 and earlier.
The problem allows a remote or local attacker to execute arbitrary
code by causing a heap-based buffer overflow via quantifier values
in regular expressions. As PCRE is a popular library, this problem
affects many applications. The Common Vulnerabilities and Exposures
(CVE) project assigned the id CAN-2005-2491 [2] to the problem.
Please check whether you are affected by running "<prefix>/bin/openpkg
rpm -q pcre". If you have the "pcre" package installed and its version
is affected (see above), we recommend that you immediately upgrade it
(see Solution) and its dependent packages (see above), too [3][4].
Solution:
Select the updated source RPM appropriate for your OpenPKG release
[5][6], fetch it from the OpenPKG FTP service [7][8] or a mirror
location, verify its integrity [9], build a corresponding binary RPM
from it [3] and update your OpenPKG installation by applying the
binary RPM [4]. For the most recent release OpenPKG 2.4, perform the
following operations to permanently fix the security problem (for
other releases adjust accordingly).
$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/2.4/UPD
ftp> get pcre-6.0-2.4.1.src.rpm
ftp> bye
$ <prefix>/bin/openpkg rpm -v --checksig pcre-6.0-2.4.1.src.rpm
$ <prefix>/bin/openpkg rpm --rebuild pcre-6.0-2.4.1.src.rpm
$ su -
# <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/pcre-6.0-2.4.1.*.rpm
Additionally, we recommend that you rebuild and reinstall
all dependent packages (see above), too [3][4].
