## Description

The CERT\_VerifyCert function in lib/certhigh/certvfy.c in Mozilla Network
Security Services (NSS) 3.15 before 3.15.3 provides an unexpected return
value for an incompatible key-usage certificate when the CERTVerifyLog
argument is valid, which might allow remote attackers to bypass intended
access restrictions via a crafted certificate.
