DSA-1556-2 perl -- heap buffer overflow

Debian Security Advisory

DSA-1556-2 perl -- heap buffer overflow

Date Reported:

24 Apr 2008

Affected Packages:

perl

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 454792.
In Mitre's CVE dictionary: CVE-2008-1927.

More information:

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 5.8.8-7etch4.

The unstable distribution (sid) will be fixed soon.

We recommend that you upgrade your perl packages.

Fixed in:

Debian GNU/Linux 4.0 (etch)
