Linux Debian vulnerability analysis and mitigation

Overview

Libelfin v0.3 was discovered to contain an integer overflow vulnerability in the load function at elf/mmap_loader.cc. This vulnerability was disclosed on March 14, 2023, and affects the Libelfin library version 0.3. The vulnerability has been assigned CVE-2023-24180 and received a CVSS v3.1 base score of 6.5 (Medium) (NVD).

Technical details

The vulnerability exists in the load function within mmap_loader.cc file. The issue occurs when handling offset and size parameters, which can be treated as u64 values. If these values are large enough, they can cause an addition overflow in the check 'if (offset + size > lim)', potentially returning a pointer to an invalid address. The vulnerability has been assigned a CVSS vector of CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H (NVD, GitHub Issue).

Impact

When exploited, this vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted ELF file. The vulnerability can be triggered by submitting a malicious ELF file that exploits the integer overflow bug, leading to program crashes or system instability (NVD, GitHub Issue).
