CVE-2026-45784 (GCVE-0-2026-45784)

Vulnerability from cvelistv5 – Published: 2026-07-17 20:26 – Updated: 2026-07-20 13:49

Title

rust-openssl: Potential out-of-bounds write in `CipherCtxRef::cipher_update_inplace` for AES-KW-PAD ciphers

Summary

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.

Severity

5.1 (Medium)

GHSA-PHQJ-4MHP-Q6MQ

Vulnerability from github – Published: 2026-05-19 19:50 – Updated: 2026-05-19 19:50

Summary

rust-openssl: Potential out-of-bounds write in `CipherCtxRef::cipher_update_inplace` for AES-KW-PAD ciphers

Details

CipherCtxRef::cipher_update_inplace 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 method was missed in the fix for GHSA-xv59-967r-8726

Severity

5.1 (Medium)
