CVE-2026-44348 | PoDoFo: Double-free vulnerability in compute_hash_to_sign()

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.

2.5 3.1 LOW
CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
