Description

Sebastian Krahmer discovered that cups-browsed incorrectly filtered remote printer names and strings. A remote attacker could use this issue to possibly execute arbitrary commands. (CVE-2014-2707)

Johannes Meixner discovered that cups-browsed ignored invalid BrowseAllow directives. This could cause it to accept browse packets from all hosts, contrary to intended configuration.

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