Description

In nss, a set of libraries designed to support cross-platform development of security-enabled client and server applications, Tyson Smith and Jesse Schwartzentruber discovered a use-after-free vulnerability that allows remote attackers to execute arbitrary code by triggering the improper removal of an NSSCertificate structure from a trust domain.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
