Several remote vulnerabilities have been discovered in the Ethereal network sniffer, which may lead to the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems:
Ilja van Sprundel discovered that the FW-1 and MQ dissectors are vulnerable to format string attacks.
Ilja van Sprundel discovered that the MOUNT dissector is vulnerable to denial of service through memory exhaustion.
Ilja van Sprundel discovered off-by-one overflows in the NCP NMAS and NDPS dissectors.
Ilja van Sprundel discovered a buffer overflow in the NFS dissector.
Ilja van Sprundel discovered that the SSH dissector is vulnerable to denial of service through an infinite loop.
For the stable distribution (sarge) these problems have been fixed in version 0.10.10-2sarge6.
For the unstable distribution (sid) these problems have been fixed in version 0.99.2-1 of wireshark, the sniffer formerly known as ethereal.
