CVE-2014-8767 [MEDIUM] tcpdump vulnerabilities
Title: tcpdump vulnerabilities
Summary: Several security issues were fixed in tcpdump.
Steffen Bauch discovered that tcpdump incorrectly handled printing OSLR
packets. A remote attacker could use this issue to cause tcpdump to crash,
resulting in a denial of service, or possibly execute arbitrary code.

CVE-2014-8768 tcpdump: denial of service in verbose mode using malformed Geonet payload
Tcpdump crash when processing Geonet payload was reported in [1].
The application decoder for the geonet protocol fails to perform external input validation and performs insufficient checking on length computations leading to an unsafe decrement and underflow in the function
geonet_print(netdissect_options *ndo, const u_char *eth, const u_char *bp, u_int length)
The affected variable is length which is later on used to print a memory chunk which eventually leads to a segfault. The function contains several unsafe computations updating the length variable.
To reproduce start tcpdump on a network interface
sudo tcpdump -i lo -s 0 -n -v
(running the program with sudo might hide the segfault message o
