DSA-853-1 ethereal Detailed Explanation for this Vulnerability Assessment Several security problems have been discovered in ethereal, a commonly used network traffic analyser. The Common Vulnerabilities and Exposures project identifies the following problems: Memory allocation errors in the LDAP dissector can cause a denial of service. Various errors in the AgentX, PER, DOCSIS, RADIUS, Telnet, IS-IS, HTTP, DCERPC, DHCP and SCTP dissectors can cause a denial of service. Various errors in the SMPP, 802.3, H1 and DHCP dissectors can cause a denial of service. Null pointer dereferences in the WBXML and GIOP dissectors can cause a denial of service. A buffer overflow and null pointer dereferences in the SMB dissector can cause a denial of service. Wrong address calculation in the BER dissector can cause an infinite loop or abortion. Format string vulnerabilities in several dissectors permit remote attackers to write to arbitrary memory locations and thus gain rights. For the old stable distribution (woody) these problems have been fixed in version 0.9.4-1woody13. For the stable distribution (sarge) these problems have been fixed in version 0.10.10-2sarge3. For the unstable distribution (sid) these problems have been fixed in version 0.10.12-2. We recommend that you upgrade your ethereal packages.
