How to fix?

Upgrade Alpine:3.17 upx to version 3.96-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream upx package and not the upx package as distributed by Alpine. See How to fix? for Alpine:3.17 relevant fixed versions and status.

PackLinuxElf64::unpack in p_lx_elf.cpp in UPX 3.95 allows remote attackers to cause a denial of service (double free), limit the ability of a malware scanner to operate on the entire original data, or possibly have unspecified other impact via a crafted file.
