NVD Description
Note: Versions mentioned in the description apply only to the upstream upx-ucl package and not the upx-ucl package as distributed by Ubuntu.
p_lx_elf.cpp in UPX 3.94 mishandles ELF headers, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted binary file, as demonstrated by an Invalid Pointer Read in PackLinuxElf64::unpack().
