Ubuntu 6.06 LTS / 7.04 / 7.10 : cpio vulnerability (USN-650-1)

High Nessus Plugin ID 36256


The remote Ubuntu host is missing a security-related patch.


A buffer overflow was discovered in cpio. If a user were tricked into opening a crafted cpio archive, an attacker could cause a denial of service via application crash, or possibly execute code with the privileges of the user invoking the program. (CVE-2007-4476).

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.


Update the affected cpio package.
