Debian DLA-1833-2 : bzip2 regression update

critical Nessus Plugin ID 126221


The remote Debian host is missing a security update.


The original fix for CVE-2019-12900 in bzip2, a high-quality block-sorting file compressor, introduces regressions when extracting certain lbzip2 files which were created with a buggy libzip2.

Please see for more information.

For Debian 8 'Jessie', this problem has been fixed in version 1.0.6-4+deb7u2.

We recommend that you upgrade your bzip2 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Upgrade the affected packages.
