CVE-2023-1255  (opens in a new tab)
CWE-126  (opens in a new tab)

How to fix?

Upgrade openssl to version 3.0.9, 3.1.1 or higher.

Overview

Affected versions of this package are vulnerable to Buffer Over-read on 64-bit ARM systems using AES-XTS cipher decryption. Attackers in control of the size and location of the ciphertext buffer can cause a crash by supplying a buffer of length 4 mod 5 at a location just before unmapped memory.

NOTE: This issue can be patched by applying the fix commits to versions 3.0 and 3.1, but no dedicated fixed release is planned until the next scheduled one.
