Title: Ethereal Multiple Protocol Dissector Vulnerabilities
Severity: HIGH
Description:
Ethereal is a multi-platform network-protocol sniffer and analyzer.
Many vulnerabilities in Ethereal have been disclosed by the vendor. The reported issues are in various protocol dissectors.
The SMB dissector is prone to an unspecified buffer overflow due to improper bounds checking of user-supplied data. This issue potentially allows remote attackers to execute arbitrary machine code in the context of the affected application.
Attackers may exploit unspecified flaws in the following protocol dissectors to cause Ethereal to enter into large or infinite loops:
- 802.3
- BER
- DHCP
- H1
- MEGACO
- SMB
- SMPP
Attackers may exploit the following protocol dissectors to cause crashes by dereferencing NULL pointers:
- CAMEL
- GIOP
- WBXML
Attackers may exploit unspecified flaws in the following protocol dissectors to cause crashes:
- AgentX
- CAMEL
- DCERPC
- DHCP
- DOCSIS
- HTTP
- IS-IS LSP
- LDAP
- NCP
- PER
- RADIUS
- SCTP
- Telnet
Several unspecified dissectors are prone to format-string vulnerabilities. These issues are due to the application's failure to properly sanitize user-supplied input before using it as format specifiers in formatted-printing functions. This issue potentially allows remote attackers to execute arbitrary machine code in the context of the affected application.
One specific format-string vulnerability resides in the AFP protocol dissector. The 'proto_item_set_text()' function uses format specifiers with user-supplied data without first properly sanitizing it. Due to the stateless nature of Ethereal, a single spoofed TCP packet on port 548 is sufficient to exploit this vulnerability. This issue is identified as CAN-2005-2367.
Several unspecified dissectors as prone to crashing the application when it tries to reassemble packets.
These issues could allow remote attackers to execute arbitrary machine code in the context of the vulnerable application. Attackers could also crash the affected application.
Various vulnerabilities affect several versions of Ethereal from 0.8.5 through to 0.10.11.
