CVE-2008-1391

Status Candidate

Overview

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.

Ubuntu Security Notice 944-1 - Maksymilian Arciemowicz discovered that the GNU C library did not correctly handle integer overflows in the strfmon function. If a user or automated system were tricked into processing a specially crafted format string, a remote attacker could crash applications, leading to a denial of service. (Ubuntu 10.04 was not affected.) Jeff Layton and Dan Rosenberg discovered that the GNU C library did not correctly handle newlines in the mntent family of functions. If a local attacker were able to inject newlines into a mount entry through other vulnerable mount helpers, they could disrupt the system or possibly gain root privileges. Dan Rosenberg discovered that the GNU C library did not correctly validate certain ELF program headers. If a user or automated system were tricked into verifying a specially crafted ELF program, a remote attacker could execute arbitrary code with user privileges.
