Critical Nessus Plugin ID 102647

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's different from CVSS.

VPR Score: 5.9

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

The following packages have been upgraded to a later upstream version:
libtasn1 (4.10).

Security Fix(es) :

- A heap-based buffer overflow flaw was found in the way the libtasn1 library decoded certain DER-encoded inputs.
A specially crafted DER- encoded input could cause an application using libtasn1 to perform an invalid read, causing the application to crash. (CVE-2015-3622)

- A stack-based buffer overflow was found in the way libtasn1 decoded certain DER encoded data. An attacker could use this flaw to crash an application using the libtasn1 library. (CVE-2015-2806)

Solution

Update the affected packages.
