A null pointer dereference may have inadvertently occurred in pk12util, and specifically in the SEC_ASN1DecodeItem_Util function, when handling malformed or improperly formatted input files. This vulnerability affects Firefox < 133 and Thunderbird < 133.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
