NVD Description

Note: Versions mentioned in the description apply only to the upstream nss-tools package and not the nss-tools package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2018.03 relevant fixed versions and status.

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.
