CVE-2022-25169

Denial of service via unchecked BPG extension lengths

Published May 16, 2022 · Updated Aug 3, 2024

Resource exhaustion in Apache Tika before 1.28.2 and 2.0.0 through 2.3.0 allows attackers to interrupt parsing via a crafted BPG file. BPGParser trusts each extension-record length, casts it to an integer, and allocates an XMP byte array without enforcing a maximum. The crafted file must reach BPGParser through an application or user-initiated parse; excessive allocation exhausts the JVM heap and terminates the Tika process.
