Synopsis :

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

Description :

It was discovered that libarchive incorrectly handled certain ISO 9660
image files. If a user were tricked into using a specially crafted ISO
9660 image file, a remote attacker could cause libarchive to crash or
possibly execute arbitrary code with user privileges. (CVE-2011-1777)

It was discovered that libarchive incorrectly handled certain tar
archive files. If a user were tricked into using a specially crafted
tar file, a remote attacker could cause libarchive to crash or
possibly execute arbitrary code with user privileges. (CVE-2011-1778).

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.

Solution :

Update the affected libarchive1 package.
