SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200608-26 (Wireshark: Multiple vulnerabilities)
The following vulnerabilities have been discovered in Wireshark.
Firstly, if the IPsec ESP parser is used it is susceptible to off-by-one errors, this parser is disabled by default; secondly, the SCSI dissector is vulnerable to an unspecified crash; and finally, the Q.2931 dissector of the SSCOP payload may use all the available memory if a port range is configured. By default, no port ranges are configured.
An attacker might be able to exploit these vulnerabilities, resulting in a crash or the execution of arbitrary code with the permissions of the user running Wireshark, possibly the root user.
Disable the SCSI and Q.2931 dissectors with the 'Analyse' and 'Enabled protocols' menus. Make sure the ESP decryption is disabled, with the 'Edit -> Preferences -> Protocols -> ESP' menu.
SolutionAll Wireshark users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-analyzer/wireshark-0.99.3'
