Multiple vulnerabilities including one buffer overflow exist in Ethereal, which may allow an attacker to run arbitrary code or crash the program.
|Package||net-analyzer/ethereal on all architectures|
|Affected versions||<= 0.10.4|
|Unaffected versions||>= 0.10.5|
Ethereal is a feature rich network protocol analyzer.
There are multiple vulnerabilities in versions of Ethereal earlier than 0.10.5, including:
An attacker could use these vulnerabilities to crash Ethereal or even execute arbitrary code with the permissions of the user running Ethereal, which could be the root user.
For a temporary workaround you can disable all affected protocol dissectors by selecting Analyze->Enabled Protocols... and deselecting them from the list. For SMB you can disable SID snooping in the SMB protocol preference. However, it is strongly recommended to upgrade to the latest stable version.
All Ethereal users should upgrade to the latest stable version:
# emerge sync # emerge -pv ">=net-analyzer/ethereal-0.10.5" # emerge ">=net-analyzer/ethereal-0.10.5"
