[ASA-201906-3] binutils: multiple issues
Arch Linux Security Advisory ASA-201906-3 ========================================= Severity: High Date : 2019-06-04 CVE-ID : CVE-2018-19931 CVE-2018-19932 CVE-2018-20002 CVE-2018-20712 Package : binutils Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-832 Summary ======= The package binutils before version 2.32-1 is vulnerable to multiple issues including arbitrary code execution and denial of service. Resolution ========== Upgrade to 2.32-1. # pacman -Syu "binutils>=2.32-1" The problems have been fixed upstream in version 2.32. Workaround ========== None. Description =========== - CVE-2018-19931 (arbitrary code execution) An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils through 2.31. There is a heap-based buffer overflow in bfd_elf32_swap_phdr_in in elfcode.h because the number of program headers is not restricted. - CVE-2018-19932 (denial of service) An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils through 2.31. There is an integer overflow and infinite loop caused by the IS_CONTAINED_BY_LMA macro in elf.c. - CVE-2018-20002 (denial of service) The _bfd_generic_read_minisymbols function in syms.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31, has a memory leak via a crafted ELF file, leading to a denial of service (memory consumption), as demonstrated by nm. - CVE-2018-20712 (denial of service) A heap-based buffer over-read exists in the function d_expression_1 in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31.1. A crafted input can cause segmentation faults, leading to denial-of- service, as demonstrated by c++filt. Impact ====== An attacker is able to crash or execute arbitrary code on a process that uses libbfd functions by providing a malicious object file.
