NVD Description

Note: Versions mentioned in the description apply only to the upstream nss-softokn-freebl package and not the nss-softokn-freebl package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the block size, a small out of bounds write could occur. This could have caused heap corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.
