Ubuntu 6.06 LTS / 8.04 LTS / 9.04 / 9.10 / 10.04 LTS : samba vulnerability (USN-987-1)

high Nessus Plugin ID 49236

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Andrew Bartlett discovered that Samba did not correctly validate the length when parsing SIDs. A remote attacker could send a specially crafted request to the server and cause a denial of service, or possibly execute arbitrary code with the privileges of the Samba service (smbd).

The default compiler options for Ubuntu 8.04 LTS and newer should reduce the vulnerability to a denial of service.

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.

Solution

Update the affected packages.
