Ubuntu 6.06 LTS / 8.04 LTS / 9.04 : samba vulnerability (USN-951-1)

Description

Jun Mao discovered that Samba did not correctly validate SMB1 packet contents. An unauthenticated remote attacker could send specially crafted network traffic that could execute arbitrary code as the root user.

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.
