According to the versions of the binutils packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  • An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. An invalid memory access exists in
    _bfd_stab_section_find_nearest_line in syms.c.
    Attackers could leverage this vulnerability to cause a denial of service (application crash) via a crafted ELF file.(CVE-2018-17358)

  • An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. a heap-based buffer over-read in bfd_getl32 in libbfd.c allows an attacker to cause a denial of service through a crafted PE file. This vulnerability can be triggered by the executable objdump.(CVE-2018-17360)

  • An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. a heap-based buffer over-read in bfd_getl32 in libbfd.c allows an attacker to cause a denial of service through a crafted PE file. This vulnerability can be triggered by the executable objdump.(CVE-2018-20623)

  • A NULL pointer dereference was discovered in elf_link_add_object_symbols in elflink.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31.1. This occurs for a crafted ET_DYN with no program headers. A specially crafted ELF file allows remote attackers to cause a denial of service, as demonstrated by ld.(CVE-2018-20651)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
