[GLSA-200407-08] Ethereal: Multiple security problems Vulnerability Scan

Vulnerability Scan Summary
Ethereal: Multiple security problems

Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200407-08
(Ethereal: Multiple security problems)

There are multiple vulnerabilities in versions of Ethereal earlier than
0.10.5, including:
In some cases the iSNS dissector could cause Ethereal to abort.
If there was no policy name for a handle for SMB SID snooping it could
cause a crash.
A malformed or missing community string could cause the SNMP dissector
to crash.


A possible hacker 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


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"

Threat Level: High
