Description:
A vulnerability has been reported in Ethereal, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially to compromise a user's system.
The vulnerability is caused due to a boundary error in the dissect_ospf_v3_address_prefix() function of the OSPF protocol dissector (packet-ospf.c) when converting received binary data to a human readable string. This can be exploited to cause a stack-based buffer overflow and may potentially allow arbitrary code execution on certain platforms.
The vulnerability has been reported in ethereal-0.10.12 RPM from Red Hat Fedora Core 3, and also in versions 0.8.20 through 0.10.13.
