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...
