[DSA853] DSA-853-1 ethereal Vulnerability Scan
Vulnerability Scan Summary
DSA-853-1 ethereal
Detailed Explanation for this Vulnerability Test
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 allow
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.
