NixOS vulnerability analysis and mitigation

CVE-2022-38533 is a vulnerability discovered in GNU Binutils before version 2.40, reported on August 13, 2022. The vulnerability involves a heap-buffer-overflow in the error function bfdgetl32 when called from the stripmain function in strip-new via a crafted file (CVE, Ubuntu).

The vulnerability is classified with a CVSS v3.1 score of 5.5 (Medium), with the vector string CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H. The issue occurs specifically in the strip utility of binutils when processing specially crafted COFF files, leading to a heap-based buffer overflow in the bfdgetl32 function ([Rapid7](https://www.rapid7.com/db/vulnerabilities/amazonlinux_2023-cve-2022-38533/), Ubuntu).

When successfully exploited, this vulnerability can lead to a Denial of Service (DoS) condition. The heap-buffer-overflow can cause the utility to crash when processing maliciously crafted files (NetApp, Rapid7).

The vulnerability was fixed in GNU Binutils version 2.40. The fix includes a sanity check for LIB in coffsetsectioncontents and improvements to handle arithmetic overflows when comparing addresses. Users are advised to upgrade to Binutils version 2.40 or later (Sourceware, Gentoo).
