(CVE-2017-14176)

Note that Nessus relies on the presence of the package as reported by the vendor.

An update of the bzr package has been released.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Bazaar through 2.7.0, when Subprocess SSH is used, allows remote attackers to execute arbitrary commands
    via a bzr+ssh URL with an initial dash character in the hostname, a related issue to CVE-2017-9800,
    CVE-2017-12836, CVE-2017-12976, CVE-2017-16228, CVE-2017-1000116, and CVE-2017-1000117. (CVE-2017-14176)

According to the version of the bzr package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - Bazaar through 2.7.0, when Subprocess SSH is used,     allows remote attackers to execute arbitrary commands     via a bzr+ssh URL with an initial dash character in the     hostname, a related issue to CVE-2017-9800,     CVE-2017-12836, CVE-2017-12976, CVE-2017-16228,     CVE-2017-1000116, and CVE-2017-1000117.(CVE-2017-14176)

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

Adam Collard discovered that Bazaar, an easy to use distributed version control system, did not correctly handle maliciously constructed bzr+ssh URLs, allowing a remote attacker to run an arbitrary shell command.

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.
