Debian DLA-1107-1 : bzr security update

high Nessus Plugin ID 103429

Language:

Synopsis

The remote Debian host is missing a security update.

Description

CVE-2013-2099

Bazaar bundles SSL certificate checking code from Python, which had a bug that could cause a denial of service via resource consumption through multiple wildcards in certificate hostnames.

CVE-2017-14176

Adam Collard found that host names in 'bzr+ssh' URLs were not parsed correctly by Bazaar, allowing remote attackers to run arbitrary code by tricking a user into a maliciously crafted URL.

For Debian 7 'Wheezy', these problems have been fixed in version 2.6.0~bzr6526-1+deb7u1.

We recommend that you upgrade your bzr 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.

Solution

Upgrade the affected packages.
