Debian: ethereal Multiple remote vulnerabilities
Summary
Several of the packet dissectors in ethereal contain string handling
bugs which could be exploited using a maliciously crafted packet to
cause ethereal to consume excessive amounts of memory, crash, or
execute arbitrary code.
These vulnerabilites were announced in the following Ethereal security
advisory:
Ethereal 0.9.4 in Debian 3.0 (woody) is affected by most of the
problems described in the advisory, including:
* The DCERPC dissector could try to allocate too much memory
while trying to decode an NDR string.
* Bad IPv4 or IPv6 prefix lengths could cause an overflow in the
OSI dissector.
* The tvb_get_nstringz0() routine incorrectly handled a
zero-length buffer size.
* The BGP, WTP, DNS, 802.11, ISAKMP, WSP, CLNP, and ISIS
dissectors handled strings improperly.
The following problems do NOT affect this version:
* The SPNEGO dissector could segfault while parsing an invalid
ASN.1 value.
* The RMI dissector handled strings improperly
as these modules are not present.
For the stable distribution (woody) these problems have been fixed in
version 0.9.4-1woody5.
The old stable distribution (potato) these problems will be fixed in a
future advisory.
For the unstable distribution (sid) these problems are fixed in
version 0.9.13-1.
We recommend that you update your ethereal package.
