- desc = 'The remote host is affected by the vulnerability described in GLSA-200412-15
- (Ethereal: Multiple vulnerabilities)
-
-
- There are multiple vulnerabilities in versions of Ethereal earlier
- than 0.10.8, including:
- Bug in DICOM dissection
- discovered by Bing could make Ethereal crash (CAN 2004-1139).
- An invalid RTP timestamp could make Ethereal hang and create a
- large temporary file (CAN 2004-1140).
- The HTTP dissector could
- access previously-freed memory (CAN 2004-1141).
- Brian Caswell
- discovered that an improperly formatted SMB could make Ethereal hang
- (CAN 2004-1142).
-
- Impact
-
- An attacker might be able to use these vulnerabilities to crash
- Ethereal, perform DoS by CPU and disk space utilization or even execute
- arbitrary code with the permissions of the user running Ethereal, which
- could be the root user.
-
- Workaround
-
- For a temporary workaround you can disable all affected protocol
- dissectors by selecting Analyze->Enabled Protocols... and deselecting
- them from the list. However, it is strongly recommended to upgrade to
- the latest stable version.

- # emerge --sync
- # emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.8"
