binutils vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.04 LTS (Available with Ubuntu Pro)
- Ubuntu 16.04 LTS (Available with Ubuntu Pro)
- Ubuntu 14.04 LTS (Available with Ubuntu Pro)

Summary:

Several security issues were fixed in GNU binutils.

Software Description:
- 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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 18.04 LTS (Available with Ubuntu Pro):
binutils 2.30-21ubuntu1~18.04.9+esm3
binutils-multiarch 2.30-21ubuntu1~18.04.9+esm3

Ubuntu 16.04 LTS (Available with Ubuntu Pro):
binutils 2.26.1-1ubuntu1~16.04.8+esm9
binutils-multiarch 2.26.1-1ubuntu1~16.04.8+esm9

Ubuntu 14.04 LTS (Available with Ubuntu Pro):
binutils 2.24-5ubuntu14.2+esm5
binutils-multiarch 2.24-5ubuntu14.2+esm5

In general, a standard system update will make all the necessary changes.
