Description:
Multiple vulnerabilities have been identified in Ethereal, which could be exploited to cause a DoS (Denial of Service) on a vulnerable system or potentially compromise it.
The vulnerabilities are caused due to various errors in the following protocol dissectors:
- DCERPC dissector (decoding NDR strings can lead to excessive memory consumption).
- OSI dissector (boundary error when handling manipulated IPv4 or IPv6 prefix lengths).
- SPNEGO (can crash when handling invalid ASN.1 values).
- BGP, WTP, DNS, 802.11, ISAKMP, WSP, CLNP, ISIS, and RMI dissectors (error in string handling)
Furthermore, an error also exists in the "tvb_get_nstringz0()" routine, when handling zero-length buffer sizes.
Solution:
