CVE-2026-6331
HMAC zero-length tag forgery in EVPDigestVerifyFinal, where a zero-length tag could be accepted as valid during HMAC verification. In the OpenSSL-compatibility HMAC verify path the supplied signature length was only checked as not exceeding the MAC length, so a zero-length or otherwise truncated...
CVE-2026-6331 HMAC zero-length tag forgery in EVP_DigestVerifyFinal
HMAC zero-length tag forgery in EVPDigestVerifyFinal, where a zero-length tag could be accepted as valid during HMAC verification. In the OpenSSL-compatibility HMAC verify path the supplied signature length was only checked as not exceeding the MAC length, so a zero-length or otherwise truncated...
Double Free
Overview Affected versions of this package are vulnerable to Double Free in the computehashtosign function. An attacker can cause heap corruption and potentially crash the application by triggering a failure in EVPDigestFinal after memory has already been freed, leading to a second free operation...
CVE-2026-44348
PoDoFo is a C++17 PDF manipulation library. From 1.0.0 to before 1.0.4, a double-free vulnerability exists in computehashtosign in src/podofo/private/OpenSSLInternalRipped.cpp. If EVPDigestFinal fails after buf has already been freed, the Error label frees buf a second time, causing heap...
CVE-2026-41681
rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.10.39 to before 0.10.78, EVPDigestFinal always writes EVPMDCTXsizectx to the out buffer. If out is smaller than that, MdCtxRef::digestfinal writes past its end, usually corrupting the stack. This is reachable from sa...
rust-openssl 安全漏洞
rust-openssl is an open-source library designed for interacting with the OpenSSL library. There were security vulnerabilities in the version of rust-openssl from 0.10.39 to 0.10.78. These vulnerabilities stemmed from the EVPDigestFinal function, which always writes EVPMDCTXsize bytes into the...
