4 October 2023

Several security issues were fixed in GNU binutils.

Releases

  o Ubuntu 18.04 ESM
  o Ubuntu 16.04 ESM
  o Ubuntu 14.04 ESM

Packages

  o binutils - GNU assembler, linker and binary utilities

Details

It was discovered that GNU binutils was not properly performing checks
when dealing with memory allocation operations, which could lead to
excessive memory consumption. An attacker could possibly use this issue
to cause a denial of service. This issue only affected Ubuntu 14.04 LTS.
( CVE-2017-17122 , CVE-2017-8421 )

It was discovered that GNU binutils was not properly performing bounds
checks when processing debug sections with objdump, which could lead to
an overflow. An attacker could possibly use this issue to cause a denial
of service or execute arbitrary code. This issue only affected Ubuntu
14.04 LTS. ( CVE-2018-20671 , CVE-2018-6543 )

It was discovered that GNU binutils contained a reachable assertion, which
could lead to an intentional assertion failure when processing certain
crafted DWARF files. An attacker could possibly use this issue to cause a
denial of service. This issue only affected Ubuntu 18.04 LTS.
( CVE-2022-35205 )

It was discovered that GNU binutils incorrectly handled memory management
operations in several of its functions, which could lead to excessive
memory consumption due to memory leaks. An attacker could possibly use
these issues to cause a denial of service.
( CVE-2022-47007 , CVE-2022-47008 , CVE-2022-47010 , CVE-2022-47011 )

It was discovered that GNU binutils was not properly performing bounds
checks when dealing with memory allocation operations, which could lead
to excessive memory consumption. An attacker could possibly use this issue
to cause a denial of service. ( CVE-2022-48063 )
