Ubuntu 6.06 LTS / 6.10 / 7.04 / 7.10 : samba vulnerability (USN-556-1)
High Nessus Plugin ID 29738
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionAlin Rad Pop discovered that Samba did not correctly check the size of reply packets to mailslot requests. If a server was configured with domain logon enabled, an unauthenticated remote attacker could send a specially crafted domain logon packet and execute arbitrary code or crash the Samba service. By default, domain logon is disabled in Ubuntu.
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.
