ECHO-07BD-5728-1AD8 Assertion failure (abort/DoS) in jxl::PlaneBase::PlaneBase() reachable only when the cjxl encoder is used to encode a maliciously crafted GIF. There is no memory corruption and no upstream fix: the upstream tracking issues (#422, #762) remain open with no merged commit, and Debian rates the issue "unimportant" with a "Negligible security impact" note and no fixed version in any suite (bookworm through sid). With no upstream remediation available and negligible impact on the libjxl decode path we ship, this is not actionable as a backport.
