K01152385 : Binutils vulnerabilities CVE-2018-8945, CVE-2018-12697, CVE-2018-12698, CVE-2018-12699, and CVE-2018-12700

Security Advisory Description

• CVE-2018-8945

The bfd_section_from_shdr function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (segmentation fault) via a large attribute section.

• CVE-2018-12697

A NULL pointer dereference (aka SEGV on unknown address 0x000000000000) was discovered in work_stuff_copy_to_from in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.30. This can occur during execution of objdump.

• CVE-2018-12698

demangle_template in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.30, allows attackers to trigger excessive memory consumption (aka OOM) during the “Create an array for saving the template argument values” XNEWVEC call. This can occur during execution of objdump.

• CVE-2018-12699

finish_stab in stabs.c in GNU Binutils 2.30 allows attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact, as demonstrated by an out-of-bounds write of 8 bytes. This can occur during execution of objdump.

• CVE-2018-12700

A Stack Exhaustion issue was discovered in debug_write_type in debug.c in GNU Binutils 2.30 because of DEBUG_KIND_INDIRECT infinite recursion.

Impact

The vulnerability allows remote attackers to cause a denial of service (DoS) on the affected system.
