AES OCB fails to encrypt some bytes
Noroxi assessment
Priority: Monitor (action score 22/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 4.8% (FIRST EPSS); higher than 91.9% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- Fixed version: openssl (AlmaLinux:8) 1:1.1.1k-7.el8_6; openssl-devel (AlmaLinux:8) 1:1.1.1k-7.el8_6; openssl-libs (AlmaLinux:8) 1:1.1.1k-7.el8_6.
- Mentioned 4 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to openssl (AlmaLinux:8) 1:1.1.1k-7.el8_6; openssl-devel (AlmaLinux:8) 1:1.1.1k-7.el8_6; openssl-libs (AlmaLinux:8) 1:1.1.1k-7.el8_6 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
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. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). Fixed in OpenSSL 1.1.1q (Affected 1.1.1-1.1.1p).
