Ubuntu 4.10 : ppp Denial of Service (USN-12-1)
High Nessus Plugin ID 20508
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionIt has been discovered that ppp does not properly verify certain data structures used in the CBCP protocol. This vulnerability could allow an attacker to cause the pppd server to crash due to an invalid memory access, leading to a denial of service. However, there is no possibility of code execution or privilege escalation.
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 ppp and / or ppp-dev packages.
