From: "fweimer at redhat dot com" <sourceware-bugzilla@sourceware.org> To: glibc-bugs@sources.redhat.com Subject: [Bug stdio/14771] New: add length sanity check to snprintf Date: Fri, 26 Oct 2012 10:06:00 -0000 [thread overview] Message-ID: <bug-14771-131@http.sourceware.org/bugzilla/> (raw) http://sourceware.org/bugzilla/show_bug.cgi?id=14771 Bug #: 14771 Summary: add length sanity check to snprintf Product: glibc Version: unspecified Status: NEW Severity: normal Priority: P2 Component: stdio AssignedTo: fweimer@redhat.com ReportedBy: fweimer@redhat.com Classification: Unclassified We should reject impossibly large size arguments for snprintf, vsprintf. This is similar to bug 13592. Passing (size_t)-1 to snprintf to emulate the sprintf behavior might actually be valid code, so this would have to be restricted to -D_FORTIFY_SOURCE mode. This is prompted by <https://lists.exim.org/lurker/message/20121026.080330.74b9147b.en.html> (CVE-2012-5671). -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
