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

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

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

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 handling the logic
behind certain memory management related operations, which could lead to
an invalid memory access. An attacker could possibly use this issue to
cause a denial of service. (CVE-2022-47695)

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)

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-2022-48065)

Update instructions:

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

Ubuntu 22.04 LTS:
   binutils                        2.38-4ubuntu2.6
   binutils-multiarch              2.38-4ubuntu2.6

Ubuntu 20.04 LTS:
   binutils                        2.34-6ubuntu1.9
   binutils-multiarch              2.34-6ubuntu1.9

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