Vulnerability Assessment Details
Detailed Explanation for this Vulnerability Assessment
Gerald Combs reported several vulnerabilities in ethereal, a popular
network traffic analyser. The Common Vulnerabilities and Exposures
project identifies the following problems:
The OID printing routine is susceptible to an off-by-one error.
The UMA and BER dissectors could go into an infinite loop.
The Network Instruments file code could overrun a buffer.
The COPS dissector contains a potential buffer overflow.
The telnet dissector contains a buffer overflow.
Bugs in the SRVLOC and AIM dissector, and in the statistics
counter could crash ethereal.
Null pointer dereferences in the SMB PIPE dissector and when
reading a malformed Sniffer capture could crash ethereal.
Null pointer dereferences in the ASN.1, GSM SMS, RPC and
ASN.1-based dissector and an invalid display filter could crash
The SNDCP dissector could cause an unintended abortion.
For the old stable distribution (woody) these problems have been fixed in
For the stable distribution (sarge) these problems have been fixed in
For the unstable distribution (sid) these problems will be fixed soon.
We recommend that you upgrade your ethereal packages.
