Vulnerability Assessment Summary
DSA-1171-1 ethereal

Detailed Explanation for this Vulnerability Assessment

Several remote vulnerabilities have been discovered in the Ethereal network
scanner, which may lead to the execution of arbitrary code. The Common
Vulnerabilities and Exposures project identifies the following problems:
It was discovered that the Q.2391 dissector is vulnerable to denial
of service caused by memory exhaustion.
It was discovered that the FC-FCS, RSVP and ISIS-LSP dissectors are
vulnerable to denial of service caused by memory exhaustion.
It was discovered that the IrDA and SMB dissectors are vulnerable to
denial of service caused by memory corruption.
It was discovered that the SLIMP3 and AgentX dissectors are vulnerable
to code injection caused by buffer overflows.
It was discovered that the BER dissector is vulnerable to denial of
service caused by an infinite loop.
It was discovered that the NCP and RTnet dissectors are vulnerable to
denial of service caused by a null pointer dereference.
It was discovered that the X11 dissector is vulnerable to denial of service
caused by a division through zero.
This update also fixes a 64 bit-specific regression in the ASN.1 decoder, which
was introduced in a previous DSA.
For the stable distribution (sarge) these problems have been fixed in
version 0.10.10-2sarge8.
For the unstable distribution (sid) these problems have been fixed in
version 0.99.2-5.1 of wireshark, the network sniffer formerly known as
ethereal.
We recommend that you upgrade your ethereal packages.
