USN-794-1: Perl vulnerability

Releases

• Ubuntu 9.04
• Ubuntu 8.10
• Ubuntu 8.04

Packages

• libcompress-raw-zlib-perl -
• perl -

Details

It was discovered that the Compress::Raw::Zlib Perl module incorrectly
handled certain zlib compressed streams. If a user or automated system were
tricked into processing a specially crafted compressed stream or file, a
remote attacker could crash the application, leading to a denial of
service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.04

• libcompress-raw-zlib-perl - 2.015-1ubuntu0.1
• perl - 5.10.0-19ubuntu1.1

Ubuntu 8.10

• libcompress-raw-zlib-perl - 2.011-2ubuntu0.1
• perl - 5.10.0-11.1ubuntu2.3

Ubuntu 8.04

• libcompress-raw-zlib-perl - 2.008-1ubuntu0.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.
