Multiple vulnerabilities were identified in Ethereal, which could be exploited by remote attackers to cause a denial of service or execute arbitrary commands.
The first issue is due to a buffer overflow error in the Zlib library when decompressing specially crafted data streams, which could be exploited, via a malformed stream embedded within network communication, to execute arbitrary commands. For additional information, see : FrSIRT/ADV-2005-0978
Various buffer overflow, format string, and null pointer vulnerabilities were identified in the LDAP, AgentX, 802.3, PER, DHCP, BER, MEGACO, GIOP, SMB, WBXML, H1, DOCSIS, SMPP, HTTP, DCERPC, CAMEL, RADIUS, Telnet, IS-IS LSP and NCP dissectors, which could be exploited by attackers to compromise a vulnerable system or cause the application to crash.
