CVE-2022-38533: 
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 bfd_getl32 when called from the strip_main 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 bfd_getl32 function (Rapid7, 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 requires local access and user interaction, specifically requiring an attacker to convince a victim to process a specially crafted COFF file using the strip utility. There is no evidence of this vulnerability being exploited in the wild (Ubuntu).

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