3. Description:
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.
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
After installing this update, applications using NSS (for example, Firefox)
must be restarted for this update to take effect.
5. Bugs fixed (https://bugzilla.redhat.com/):
1471171 - CVE-2017-7805 nss: Potential use-after-free in TLS 1.2 server when verifying client authentication
