How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream xpdf package and not the xpdf package as distributed by Alpine. See How to fix? for Alpine:3.21 relevant fixed versions and status.

Xpdf prior to version 4.04 contains an integer overflow in the JBIG2 decoder (JBIG2Stream::readTextRegionSeg() in JBIG2Stream.cc). Processing a specially crafted PDF file or JBIG2 image could lead to a crash or the execution of arbitrary code. This is similar to the vulnerability described by CVE-2021-30860 (Apple CoreGraphics).
