Summary
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.

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-\u003emmap_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-\u003emmap_base, the subsequent PT_LOAD segment(s) end up being mapped above mm-\u003emmap_base into the are that is supposed to be the \\\"gap\\\" between the stack and the binary.\"},{\"lang\":\"es\",\"value\":\"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). Esta vulnerabilidad en los kernels se parche\u00f3 en abril de 2015 por el commit a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (aplicado a Linux 3.10.77 en mayo de 2015), pero no se reconoci\u00f3 como amenaza de seguridad. Con CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE habilitado y una estrategia vertical normal de asignaci\u00f3n de direcciones, load_elf_binary() intentar\u00e1 mapear un binario PIE en un rango de direcciones inmediatamente inferior a mm-\u003emmap_base. Por desgracia, load_elf_ binary() no tiene en cuenta la necesidad de asignar el suficiente espacio para todo el binario, lo que significa que, estando el primer segmento PT_LOAD est\u00e1 mapeado bajo
