Debian Security Advisory DSA-1556-2                  security@...ian.org

Package        : perl
Vulnerability  : heap buffer overflow
Problem type   : local (remote)
Debian-specific: no
CVE Id         : CVE-2008-1927
Debian Bug     : 454792

An editorial mistake resulted in DSA-1556-1 not correctly applying the
required change, making it ineffective.  This DSA has been reissued as
DSA-1556-2.  We apologize for the inconvenience.  The text of the
original DSA follows.

It has been discovered that the Perl interpreter may encounter a buffer
overflow condition when compiling certain regular expressions containing
Unicode characters.  This also happens if the offending characters are
contained in a variable reference protected by the \Q...\E quoting
construct.  When encountering this condition, the Perl interpreter
typically crashes, but arbitrary code execution cannot be ruled out.

For the stable distribution (etch), this problem has been fixed in
version 5.8.8-7etch3.

The unstable distribution (sid) will be fixed soon.

We recommend that you upgrade your perl packages.

Upgrade instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
