Doc Text:
A flaw was found in PoDoFo, a C++17 PDF manipulation library. A double-free vulnerability exists in the `compute_hash_to_sign()` function. This can occur if `EVP_DigestFinal` fails after a buffer has already been freed, leading to heap corruption. This vulnerability could allow a local attacker to cause a denial of service.

Description OSIDB Bzimport 2026-05-14 17:01:46 UTC
PoDoFo is a C++17 PDF manipulation library. From 1.0.0 to before 1.0.4, a double-free vulnerability exists in compute_hash_to_sign() in src/podofo/private/OpenSSLInternal_Ripped.cpp. If EVP_DigestFinal fails after buf has already been freed, the Error label frees buf a second time, causing heap corruption. This vulnerability is fixed in 1.0.4.
