Description Jan Lieskovsky 2009-09-21 16:59:57 UTC
Common Vulnerabilities and Exposures assigned an identifier CVE-2008-1391 to
the following vulnerability:

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.


Comment 2 Jan Lieskovsky 2009-09-21 17:06:06 UTC

Red Hat does not consider this to be a security issue. Properly written
application should not use arbitrary untrusted data as part of the format
string passed to functions as strfmon or printf family functions.

Comment 5 Tomas Hoger 2011-02-04 19:11:40 UTC
glibc variants of this *BSD libc issues reported in SecurityReason Advisory 67 got separate CVE ids CVE-2009-4881 (bug #599095) and CVE-2009-4880 (bug #599070).
