CVE-2017-12898 (Other, published 2017-09-14T06:29Z)
Description: value: The NFS parser in tcpdump before 4.9.2 has a buffer over-read in print-nfs.c:interp_reply().
Severity: HIGH (CVSS v3 base score: 9.8)
Weakness: CWE-125 \u2014 Out-of-bounds Read
The product reads data past the end, or before the beginning, of the intended buffer.

Commit message: CVE-2017-12898/NFS: Fix bounds checking.

Fix the bounds checking for the NFSv3 WRITE procedure to check whether the
length of the opaque data being written is present in the captured data,
not just whether the byte count is present in the captured data.
furthest forward in the packet, not the item before it.  (This also lets
us eliminate the check for the "stable" argument being present in the
captured data; rewrite the code to print that to make it a bit clearer.)

Check that the entire ar_stat field is present in the capture.

Note that parse_wcc_attr() is called after we've already checked whether
the wcc_data is present.

Check before fetching the "access" part of the NFSv3 ACCESS results.
This fixes a buffer over-read discovered by Kamil Frankowicz.

Include a test for the "check before fetching the "access" part..." fix,
using the capture supplied by the reporter(s).


Vulnerable code:
				ND_TCHECK(dp[2]);
					dp += 3;
					ND_TCHECK(dp[0]);
							NULL, EXTRACT_32BITS(dp))));
	ND_TCHECK2(dp[0], 0);
		if (!er)

Fixed code:
				ND_TCHECK(dp[4]);
							NULL, EXTRACT_32BITS(&dp[3]))));
	ND_TCHECK(dp[0]);
	/* Our caller has already checked this */
		if (!er) {
			ND_TCHECK(dp[0]);
		}
