Verapdf Parser
Monthly
Denial-of-service in veraPDF-parser allows a remote unauthenticated attacker to crash or hang the PDF validation service by submitting a crafted PDF containing a Type 1 font whose /FontDescriptor /FontFile PostScript program exploits one of three unbounded resource primitives: a massive array allocation, a zero-increment for-loop, or a self-referential recursive user-dictionary lookup. All veraPDF-parser releases prior to 1.30.2 and 1.31.23 are affected across both active version branches. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis; vendor-released patches exist for both branches.
Memory and CPU exhaustion in veraPDF-parser's embedded PostScript interpreter allows remote unauthenticated attackers to crash the PDF validator by submitting a single crafted PDF. All 1.30.x releases prior to 1.30.2 and all 1.31.x releases prior to 1.31.23 of the Maven artifact org.verapdf:parser are affected. No public exploit code has been confirmed at time of analysis, but the GHSA advisory discloses the exact operator names, payload byte sequence, and affected source line numbers, making independent reproduction trivial without requiring any structural PDF framing.
