CVE-2021-43315: Improper Restriction of Operations within the Bounds of a Memory Buffer

A heap-based buffer overflows was discovered in upx, during the generic pointer 'p' points to an inaccessible address in func getle32. The problem is essentially caused in PackLinuxElf32::elflookup at plxelf.cpp:5349...

CVE-2021-43314

CVE-2021-43314 describes a heap-based buffer overflow in UPX, triggered in PackLinuxElf32::elf_lookup() via an inaccessible address addressed by the generic pointer p in get_le32() (p_lx_elf.cpp:5368). The issue is under UPX ELF32 parsing and, per connected advisories, was addressed by updating U...
