From 0.10.0 to before 0.10.79, CipherCtxRef::cipher_update, CipherCtxRef::cipher_update_vec, and symm::Crypter::update incorrectly sized output buffers when used with AES key-wrap-with-padding ciphers (EVP_aes_{128,192,256}_wrap_pad). For a non-multiple-of-8 input, OpenSSL writes up to 7 bytes past the end of the caller's buffer or Vec, producing attacker-controllable heap corruption when the plaintext length is attacker-influenced. This only impacts users using AES key-wrap-with-padding ciphers. This vulnerability is fixed in 0.10.79.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","score":5.1},"cvss_v3":null,"cwes":["CWE-122"],"references":["https://github.com/rust-openssl/rust-openssl/security/advisories/GHSA-xv59-967r-8726"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-44662","score":0.00172,"percentile":0.06619,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-xv59-967r-8726","url":"https://osv.dev/vulnerability/GHSA-xv59-967r-8726","summary":"rust-openssl vulnerable to heap buffer overflow when encrypting with AES key-wrap-with-padding","modified":"2026-09-10T03:51:07.319185525Z","packages":[{"ecosystem":"crates.io","name":"openssl","purl":"pkg:cargo/openssl","ranges":[">=0.10.0 <0.10.79"],"fixed":["0.10.79"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
