Debian DSA-324-1 : ethereal - several vulnerabilities
critical Nessus Plugin ID 15161
Synopsis
The remote Debian host is missing a security-related update.Description
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 vulnerabilities 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.
Solution
For the stable distribution (woody) these problems have been fixed in version 0.9.4-1woody5.For the old stable distribution (potato) these problems will be fixed in a future advisory.
We recommend that you update your ethereal package.
