CVE-2011-1767
First published: Thu May 05 2011(Updated: )
Description: 1) <a href="https://access.redhat.com/security/cve/CVE-2011-1767">CVE-2011-1767</a> gre: fix netns vs proto registration ordering GRE protocol receive hook can be called right after protocol addition is done. If netns stuff is not yet initialized, we're going to oops in net_generic(). This is remotely oopsable if ip_gre is compiled as module and packet comes at unfortunate moment of module loading. Upstream commit: <a href="http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=c2892f02">http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=c2892f02</a> References: <a href="http://www.openwall.com/lists/oss-security/2010/02/18/3">http://www.openwall.com/lists/oss-security/2010/02/18/3</a> <a href="http://patchwork.ozlabs.org/patch/45553/">http://patchwork.ozlabs.org/patch/45553/</a> 2) <a href="https://access.redhat.com/security/cve/CVE-2011-1768">CVE-2011-1768</a> tunnels: fix netns vs proto registration ordering Same stuff as in ip_gre patch: receive hook can be called before netns setup is done, oopsing in net_generic().
