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

privileges of the user invoking the program. (CVE-2007-4476)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 7.10

In general, a standard system upgrade is sufficient to effect the
necessary changes.
