CVE-2020-10223Network attack vector

Memory disclosure via JBIG2Decode heap corruption

Published Mar 8, 2020 · Updated Aug 4, 2024

Heap corruption in Nitro Pro before 13.13.2.242 allows remote attackers to expose memory contents via a crafted PDF document. The CNxJBIG2DecodeStream path in npdf.dll corrupts heap memory while decoding attacker-controlled JBIG2 data; public sources do not disclose the faulty operation. A target must open the malicious PDF, and the vendor bounds the demonstrated consequence to potential memory disclosure.
