====================================================== Name: CVE-2008-3911 Status: Candidate URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3911 Reference: MLIST:[linux-kernel] 20080830 Re: buffer overflow in /proc/sys/sunrpc/transports Reference: URL:http://lkml.org/lkml/2008/8/30/184 Reference: MLIST:[linux-kernel] 20080830 buffer overflow in /proc/sys/sunrpc/transports Reference: URL:http://lkml.org/lkml/2008/8/30/140 Reference: MLIST:[oss-security] 20080904 CVE request: kernel: sunrpc: fix possible overrun on read of /proc/sys/sunrpc/transports Reference: URL:http://www.openwall.com/lists/oss-security/2008/09/04/2 Reference: CONFIRM:http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=27df6f25ff218072e0e879a96beeb398a79cdbc8 The proc_do_xprt function in net/sunrpc/sysctl.c in the Linux kernel 2.6.26.3 does not check the length of a certain buffer obtained from userspace, which allows local users to overflow a stack-based buffer and have unspecified other impact via a crafted read system call for the /proc/sys/sunrpc/transports file.
