CVE-2022-4741Network attack vector

Service interruption via unbounded document reads

Published Dec 25, 2022 · Updated Aug 3, 2024

Uncontrolled memory allocation in Sajari docconv before 1.2.1 allows remote attackers to interrupt docd via a crafted document. ConvertDocx, ConvertODT, and ConvertPages read entire input streams into memory, while XMLToText and XMLToMap pass unbounded streams to XML decoders. Exploitation requires docd to process attacker-supplied DOCX, ODT, Pages, or XML content and can exhaust memory, causing a service crash.
