In Mitre's CVE dictionary: CVE-2013-2099, CVE-2017-14176.
More information:
  • 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.
