Synopsis
Ethereal is vulnerable to numerous vulnerabilities potentially
resulting in the execution of arbitrary code or abnormal termination.
Background
Ethereal is a feature rich network protocol analyzer.
Affected packages
Package / Vulnerable / Unaffected
1 net-analyzer/ethereal < 0.10.11 >= 0.10.11
Description
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, CSP,
PKIX1Explitit, PKIX Qualified, X.509, Q.931, MEGAC, 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
NETLGN dissectors are vulnerable to pointer handling errors.
* The LMP, KINK, MGCP, RSVP, SRVLC, EIGRP, MEGAC, DLSw, NCP and
L2TP dissectors are vulnerable to looping problems.
* The Telnet and DHCP dissectors could abort.
* 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 DICM, NDPS and ICEP dissectors are vulnerable to memory
handling errors.
* The GSM MAP, AIM, Fibre Channel,SRVLC, NDPS, LDAP and NTLMSSP
dissectors could terminate abnormallly.
Impact
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.
Workaround
There is no known workaround at this time.
Resolution
All Ethereal users should upgrade to the latest version:
# emerge
# emerge ">=net-analyzer/ethereal-0.10.11"
