{"id":"UBUNTU-CVE-2026-45784","details":"rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.10.50 until 0.10.80, CipherCtxRef::cipher_update_inplace in openssl/src/cipher_ctx.rs 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 issue is fixed in version 0.10.80.","modified":"2026-07-31T14:36:53.437228038Z","published":"2026-07-17T21:17:00Z","upstream":["CVE-2026-45784"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-45784"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-45784"},{"type":"REPORT","url":"https://github.com/rust-openssl/rust-openssl/security/advisories/GHSA-phqj-4mhp-q6mq"},{"type":"REPORT","url":"https://github.com/rust-openssl/rust-openssl/pull/2638"}],"affected":[{"package":{"name":"rust-openssl","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/rust-openssl?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.23-1","0.10.23-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"librust-openssl-dev","binary_version":"0.10.23-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-45784.json"}},{"package":{"name":"rust-openssl","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/rust-openssl?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.29-1","0.10.36-1","0.10.36-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.10.36-1ubuntu0.1~esm1","binary_name":"librust-openssl-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-45784.json"}},{"package":{"name":"rust-openssl","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/rust-openssl?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.45-1","0.10.57-1","0.10.57-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"librust-openssl-dev","binary_version":"0.10.57-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-45784.json"}},{"package":{"name":"rust-openssl","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/rust-openssl?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.72-1","0.10.73-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.10.73-1","binary_name":"librust-openssl-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-45784.json"}}],"schema_version":"1.8.0","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"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
