Ubuntu 16.04 LTS / 18.04 LTS : libiberty vulnerabilities (USN-4326-1)

high Nessus Plugin ID 135398

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4326-1 advisory.

 It was discovered that libiberty incorrectly handled parsing certain binaries. If a user or automated system were tricked into processing a specially crafted binary, a remote attacker could use this issue to cause libiberty to crash, resulting in a denial of service, or possibly execute arbitrary code

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected libiberty-dev package.
