A heap-based buffer overflow was found in the ASN.1 parsing code of NSS. A remote attacker could create a specially-crafted certificate, which when parsed by NSS, could the application linked with NSS to crash or potentially execute code with the permission of the user running such an application. Applications such as web browsers which parse untrusted web content are specially vulnerable to this issue.
Created attachment 1129399 [details] upstream patch on top of nss 3.21, from nss 3.21.1
