Description

Wojciech Purczynski discovered that the vmsplice system call did not properly perform verification of user-memory pointers. A local attacker could exploit this to overwrite arbitrary kernel memory and gain root privileges. (CVE-2008-0600).

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.
