Subject: CVE REJECT request: CVE-2013-4588
Hello,
CVE-2013-4588 was assigned to a stack overflow flaw in the Linux kernel.
-> http://seclists.org/fulldisclosure/2013/Nov/77
===
Kernel: net: ipvs: stack buffer overflow
Linux kernel built with the IP Virtual Server(CONFIG_IP_VS) support is
vulnerable to a buffer overflow flaw. It could occur while setting or
retrieving socket options via setsockopt(2) or getsockopt(2) calls.
Though a user needs to have CAP_NET_ADMIN privileges to perform these IP_VS
operations.
Upstream fix:
-------------
-> https://git.kernel.org/linus/04bcef2a83f40c6db24222b27a52892cba39dffb
===
The bounds check added by the above patch are found to be redundant, as the
same is done in routine 'nf_sockopt_find'. [1]
+ if (cmd < IP_VS_BASE_CTL || cmd > IP_VS_SO_SET_MAX)
+ return -EINVAL;
+ if (len < 0 || len > MAX_ARG_LEN)
+ return -EINVAL;
[1] https://lkml.org/lkml/2009/9/30/265
That makes it a security non-issue. Please kindly reject this CVE.
Thank you.
