Details:

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
(https://access.redhat.com/security/cve/CVE-2017-7805).

According to the Red Hat Bugzilla page about this vulnerability
(https://bugzilla.redhat.com/show_bug.cgi?id=1471171), this was fixed by Mozilla
in NSS commit 839200ce0943166a079284bdf45dcc37bb672925
(https://hg.mozilla.org/projects/nss/rev/839200ce0943166a079284bdf45dcc37bb672925).
This commit has been applied in version 3.33 of the NSS library.
