Description:Summary:
The remote host is missing an update for the Debian 'bzr' package(s) announced via the DLA-1107-1 advisory.

Vulnerability Insight:
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.
