USN-6581-1: GNU binutils vulnerabilities

Releases

• Ubuntu 22.04 LTS
• Ubuntu 20.04 LTS

Packages

• binutils - GNU assembler, linker and binary utilities

Details

It was discovered that GNU binutils was not properly performing bounds
checks in several functions, which could lead to a buffer overflow. An
attacker could possibly use this issue to cause a denial of service,
expose sensitive information or execute arbitrary code.
(CVE-2022-44840, CVE-2022-45703)

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)

Update instructions

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

Ubuntu 22.04

• binutils - 2.38-4ubuntu2.5
• binutils-multiarch - 2.38-4ubuntu2.5

Ubuntu 20.04

• binutils - 2.34-6ubuntu1.8
• binutils-multiarch - 2.34-6ubuntu1.8

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