medium Nessus Plugin ID 37746
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

USN-700-1 fixed vulnerabilities in Perl. Due to problems with the Ubuntu 8.04 build, some Perl .ph files were missing from the resulting update. This update fixes the problem. We apologize for the inconvenience.

Jonathan Smith discovered that the Archive::Tar Perl module did not correctly handle symlinks when extracting archives. If a user or automated system were tricked into opening a specially crafted tar file, a remote attacker could over-write arbitrary files.
(CVE-2007-4829)

Tavis Ormandy and Will Drewry discovered that Perl did not correctly handle certain utf8 characters in regular expressions. If a user or automated system were tricked into using a specially crafted expression, a remote attacker could crash the application, leading to a denial of service.
Ubuntu 8.10 was not affected by this issue. (CVE-2008-1927)

A race condition was discovered in the File::Path Perl module's rmtree function. If a local attacker successfully raced another user's call of rmtree, they could create arbitrary setuid binaries. Ubuntu 6.06 and 8.10 were not affected by this issue. (CVE-2008-5302)

A race condition was discovered in the File::Path Perl module's rmtree function. If a local attacker successfully raced another user's call of rmtree, they could delete arbitrary files. Ubuntu 6.06 was not affected by this issue.
(CVE-2008-5303).

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 packages.
