Language:

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 3.6

Synopsis

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

Description

Hanno Bock discovered that Libtasn1 incorrectly handled certain ASN.1 data. A remote attacker could possibly exploit this with specially crafted ASN.1 data and cause applications using Libtasn1 to crash, resulting in a denial of service, or possibly execute arbitrary code.

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 libtasn1-3 and / or libtasn1-6 packages.
