FKIE_CVE-2019-11745
Vulnerability from fkie_nvd - Published: 2020-01-08 20:15 - Updated: 2026-06-17 02:13
Severity
Summary
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.
