{"id":"GHSA-xv59-967r-8726","summary":"rust-openssl vulnerable to heap buffer overflow when encrypting with AES key-wrap-with-padding","details":"`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.\n\nThis only impacts users using AES key-wrap-with-padding ciphers.","aliases":["CVE-2026-44662"],"modified":"2026-07-17T21:13:34.521937137Z","published":"2026-05-07T22:33:51Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-05-07T22:33:51Z","nvd_published_at":"2026-05-14T21:16:47Z","cwe_ids":["CWE-122"],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/rust-openssl/rust-openssl/security/advisories/GHSA-xv59-967r-8726"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44662"},{"type":"PACKAGE","url":"https://github.com/rust-openssl/rust-openssl"}],"affected":[{"package":{"name":"openssl","ecosystem":"crates.io","purl":"pkg:cargo/openssl"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.10.0"},{"fixed":"0.10.79"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-xv59-967r-8726/GHSA-xv59-967r-8726.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
