More than fifty vulnerabilities were reported in Ethereal, which could be exploited by remote attackers to cause a denial of service and potentially execute arbitrary commands. DETAILS Vulnerable Systems: * Ethereal versions 0.8.14 up to 0.10.10 Immune Systems: * Ethereal version 0.10.11 It may be possible to make Ethereal crash, use up available memory, or run arbitrary code by injecting a purposefully malformed packet onto the wire or by convincing someone to read a malformed packet trace file. Affected Dissectors: * The ANSI A dissector was susceptible to format string vulnerabilities. Discovered by Bryan Fulton. Versions affected: 0.9.15 to 0.10.10 * The GSM MAP dissector could crash.
