Summary0001047: Qemu and other related packages
Description

I was examining the filesquash system offirmware of d-link DSL-2750U router downloaded from
ftp://support.dlink.co.in/broadband/DSL-2750U/firmware/DSL-2750U_IN_1.10_B038_K8B_0K-IN-00-2916_20110822.zip

Extracted using Binwalk v1.2.2-1.
Emulating with qemu-user-static package using qemu-mips which resulted in error
Invalid ELF image for this architecture.

Steps To Reproduce

A quick grep of Qemu’s source quickly found the culprit in linux-user/elfload.c:

static bool elf_check_ehdr(struct elfhdr *ehdr)
{
return (elf_check_arch(ehdr->e_machine)
&& ehdr->e_ehsize == sizeof(struct elfhdr)
&& ehdr->e_phentsize == sizeof(struct elf_phdr)
&& ehdr->e_shentsize == sizeof(struct elf_shdr)
&& (ehdr->e_type == ET_EXEC || ehdr->e_type == ET_DYN));
}

Removing the line "&& ehdr->e_shentsize == sizeof(struct elf_shdr)" and recompiling did the trick.

Additional Information

Please apply this patch in Qemu and related packages

This is not a "major" severity. Please keep things in perspective.
