CVE-2008-1391
FreeBSD 6.x-7.x and NetBSD 4.x - Integer Overflow in strfmon and printf Format Handling
Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2008-1391. PoCs published by Maksymilian Arciemowicz.
AI-analyzed exploit summary This exploit demonstrates an integer overflow vulnerability in the `strfmon` function in multiple BSD platforms. By providing a maliciously crafted format string, an attacker can trigger a buffer overflow, potentially leading to arbitrary code execution or a denial-of-service condition.
Description
Multiple integer overflows in libc in NetBSD 4.x, FreeBSD 6.x and 7.x, and probably other BSD and Apple Mac OS platforms allow context-dependent attackers to execute arbitrary code via large values of certain integer fields in the format argument to (1) the strfmon function in lib/libc/stdlib/strfmon.c, related to the GET_NUMBER macro; and (2) the printf function, related to left_prec and right_prec.
