CVE-2022-32292: 
NixOS vulnerability analysis and mitigation

Overview

CVE-2022-32292 affects ConnMan through version 1.41, where remote attackers can exploit a heap-based buffer overflow vulnerability in the gweb component's received_data function. The vulnerability was discovered in 2022 and received a CVSS v3.1 base score of 9.8 (CRITICAL) (NVD, CVE).

Technical details

The vulnerability stems from a mismatch in handling binary versus C-string data with memchr and strlen functions, causing pos, count, and bytes_read variables to become out of sync, resulting in a heap overflow. The issue specifically occurs in the gweb component's received_data function when processing HTTP requests (Kernel Patch).

Impact

The vulnerability allows remote attackers to execute arbitrary code through specially crafted HTTP requests sent to the gweb component. Given the CVSS score of 9.8, this represents a critical security risk with potential for complete system compromise (NVD).

Mitigation and workarounds

The vulnerability has been fixed in versions after 1.41. Multiple Linux distributions have released security updates, including Debian (version 1.36-2.2+deb11u1), Gentoo (version 1.42_pre20220801), and SUSE. Users are advised to upgrade to the patched versions (Debian Advisory, Gentoo Advisory).
