Ubuntu 14.04 LTS / 16.04 LTS / 17.04 : git vulnerability (USN-3387-1)
Medium Nessus Plugin ID 102423
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionBrian Neel, Joern Schneeweisz, and Jeff King discovered that Git did not properly handle host names in 'ssh://' URLs. A remote attacker could use this to construct a git repository that when accessed could run arbitrary code with the privileges of the user.
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.
SolutionUpdate the affected git package.
