All supported architectures
Ethereal is vulnerable to numerous vulnerabilities potentially resulting in
the execution of arbitrary code or abnormal termination.
Ethereal is a feature rich network protocol analyzer.
There are numerous vulnerabilities in versions of Ethereal prior
to 0.10.11, including:
- The ANSI A and DHCP dissectors are
vulnerable to format string vulnerabilities.
- The DISTCC,
FCELS, SIP, ISIS, CMIP, CMP, CMS, CRMF, ESS, OCSP, PKIX1Explitit, PKIX
Qualified, X.509, Q.931, MEGACO, NCP, ISUP, TCAP and Presentation
dissectors are vulnerable to buffer overflows.
- The KINK, WSP,
SMB Mailslot, H.245, MGCP, Q.931, RPC, GSM and SMB NETLOGON dissectors
are vulnerable to pointer handling errors.
- The LMP, KINK,
MGCP, RSVP, SRVLOC, EIGRP, MEGACO, DLSw, NCP and L2TP dissectors are
vulnerable to looping problems.
- The Telnet and DHCP dissectors
- The TZSP, Bittorrent, SMB, MGCP and ISUP
dissectors could cause a segmentation fault.
- The WSP, 802.3
Slow protocols, BER, SMB Mailslot, SMB, NDPS, IAX2, RADIUS, SMB PIPE,
MRDISC and TCAP dissectors could throw assertions.
- The DICOM,
NDPS and ICEP dissectors are vulnerable to memory handling errors.
- The GSM MAP, AIM, Fibre Channel,SRVLOC, NDPS, LDAP and NTLMSSP
dissectors could terminate abnormallly.
An attacker might be able to use these vulnerabilities to crash
Ethereal and execute arbitrary code with the permissions of the user
running Ethereal, which could be the root user.
There is no known workaround at this time.
All Ethereal users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.11"
