| Name | CVE-2008-1391 |
| 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. |
| Source | CVE (at NVD; oss-sec, fulldisc, OSVDB, EDB, Metasploit, Red Hat, Ubuntu, Gentoo, SuSE, Mageia, more) |
| References | DSA-2058-1 |
| NVD severity | high (attack range: remote) |
| Debian/oldstable | not vulnerable. |
| Debian/stable | not vulnerable. |
| Debian/testing | not vulnerable. |
| Debian/unstable | not vulnerable. |
Vulnerable and fixed packages
The table below lists information on source packages.
| Source Package | Release | Version | Status |
|---|
| eglibc (PTS) | squeeze | 2.11.3-4 | fixed |
| squeeze (lts) | 2.11.3-4+deb6u4 | fixed |
| wheezy | 2.13-38+deb7u6 | fixed |
| wheezy (security) | 2.13-38+deb7u8 | fixed |

The information above is based on the following data on fixed versions.
| Package | Type | Release | Fixed Version | Urgency | Origin | Debian Bugs |
|---|
| eglibc | source | (unstable) | 2.11-1 | low | | |
| glibc | source | (unstable) | 2.11-1 | low | | |
| glibc | source | lenny | 2.7-18lenny4 | high | DSA-2058-1 | |
| kfreebsd-6 | source | (unstable) | (not affected) | | | |
| kfreebsd-7 | source | (unstable) | (not affected) | | | |
Notes
- kfreebsd-6 <not-affected> (see bug #483152)
- kfreebsd-7 <not-affected> (see bug #483152)
[lenny] - glibc <no-dsa> (minor issue)
not sure if it is a security bug, an attacker should not be able to change the format string
