Ubuntu 4.10 / 5.04 / 5.10 : postgresql-7.4, postgresql-8.0, postgresql vulnerability (USN-258-1)
Low Nessus Plugin ID 21066
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionAkio Ishida discovered that the SET SESSION AUTHORIZATION command did not properly verify the validity of its argument. An authenticated PostgreSQL user could exploit this to crash the server.
However, this does not affect the official binary Ubuntu packages. The crash can only be triggered if the source package is rebuilt with assertions enabled (which is not the case in the official binary packages).
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 packages.
