Descriptions

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().

p_lx_elf.cpp en UPX 3.94 no gestiona correctamente las cabeceras ELF, lo que permite que atacantes remotos provoquen una denegación de servicio (cierre inesperado de la aplicación) o que provoquen otro impacto sin especificar mediante un archivo binario manipulado, tal y como demuestra una lectura de puntero inválida en PackLinuxElf64::unpack().
