CentOS Errata and Security Advisory CESA-2017:2832
Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications.
Security Fix(es):
- A use-after-free flaw was found in the TLS 1.2 implementation in the NSS library when client authentication was used. A malicious client could use this flaw to cause an application compiled against NSS to crash or, potentially, execute arbitrary code with the permission of the user running the application. (CVE-2017-7805)
Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges Martin Thomson as the original reporter.
