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

  - There's a flaw in binutils /bfd/pef.c. An attacker who is able to submit a crafted input file to be     processed by the objdump program could cause a null pointer dereference. The greatest threat from this     flaw is to application availability. This flaw affects binutils versions prior to 2.34. (CVE-2020-35495)

  - There's a flaw in bfd_pef_scan_start_address() of bfd/pef.c in binutils which could allow an attacker who     is able to submit a crafted file to be processed by objdump to cause a NULL pointer dereference. The     greatest threat of this flaw is to application availability. This flaw affects binutils versions prior to     2.34. (CVE-2020-35496)

  - There's a flaw in bfd_pef_parse_function_stubs of bfd/pef.c in binutils in versions prior to 2.34 which     could allow an attacker who is able to submit a crafted file to be processed by objdump to cause a NULL     pointer dereference. The greatest threat of this flaw is to application availability. (CVE-2020-35507)

  - There's a flaw in the BFD library of binutils in versions before 2.36. An attacker who supplies a crafted     file to an application linked with BFD, and using the DWARF functionality, could cause an impact to system     availability by way of excessive memory consumption. (CVE-2021-3487)

  - An out of bounds flaw was found in GNU binutils objdump utility version 2.36. An attacker could use this     flaw and pass a large section to avr_elf32_load_records_from_section() probably resulting in a crash or in     some cases memory corruption. The highest threat from this vulnerability is to integrity as well as system     availability. (CVE-2021-3549)
