CVE-2017-1000253 – Linux Kernel PIE Stack Buffer Corruption Vulnerability
https://notcve.org/view.php?id=CVE-2017-1000253
Linux distributions that have not patched their long-term kernels with https://git.kernel.org/linus/a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (committed on April 14, 2015). This kernel vulnerability was fixed in April 2015 by commit a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (backported to Linux 3.10.77 in May 2015), but it was not recognized as a security threat. With CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE enabled, and a normal top-down address allocation strategy, load_elf_binary() will attempt to map a PIE binary into an address range immediately below mm->mmap_base. Unfortunately, load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary which means that, while the first PT_LOAD segment is mapped below mm->mmap_base, the subsequent PT_LOAD segment(s) end up being mapped above mm->mmap_base into the are that is supposed to be the "gap" between the stack and the binary. Existe una vulnerabilidad en las distribuciones de Linux que no han parcheado sus kernels de largo mantenimiento con https://git.kernel.org/linus/a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (confirmada el 14 de abril de 2015). • https://www.exploit-db.com/exploits/42887 https://github.com/RicterZ/PIE-Stack-Clash-CVE-2017-1000253 https://github.com/sxlmnwb/CVE-2017-1000253 http://www.securityfocus.com/bid/101010 http://www.securitytracker.com/id/1039434 https://access.redhat.com/errata/RHSA-2017:2793 https://access.redhat.com/errata/RHSA-2017:2794 https://access.redhat.com/errata/RHSA-2017:2795 https://access.redhat.com/errata/RHSA-2017:2796 https://access.redhat.com/errata/RHSA-2017:2797 https • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
