Ubuntu 4.10 : samba vulnerability (USN-41-1)
Critical Nessus Plugin ID 20658
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionGreg MacManus discovered an integer overflow in Samba's smbd daemon.
Requesting a very large number of access control descriptors from the server caused an integer overflow, which resulted in a memory allocation being too short, thus causing a buffer overflow. By sending carefully crafted data, an attacker could exploit this to execute arbitrary code on the server with full root permissions.
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.
