Ubuntu 5.04 / 5.10 / 6.06 LTS : gnupg vulnerability (USN-304-1)
Medium Nessus Plugin ID 27879
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionEvgeny Legerov discovered that GnuPG did not sufficiently check overly large user ID packets. Specially crafted user IDs caused a buffer overflow. By tricking an user or remote automated system into processing a malicous GnuPG message, an attacker could exploit this to crash GnuPG or possibly even execute arbitrary code.
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 gnupg package.
