MGASA-2022-0255 - Updated openssl packages fix security vulnerability

Publication date: 12 Jul 2022
URL: https://advisories.mageia.org/MGASA-2022-0255.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2022-2097

AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised
implementation will not encrypt the entirety of the data under some
circumstances. This could reveal sixteen bytes of data that was
preexisting in the memory that wasn't written. In the special case of "in
place" encryption, sixteen bytes of the plaintext would be revealed. Since
OpenSSL does not support OCB based cipher suites for TLS and DTLS, they
are both unaffected. (CVE-2022-2097)
