Gentoo Linux Security Advisory

Title: Ethereal: Numerous vulnerabilities (GLSA 200505-03)
Severity: high
Exploitable: remote
Date: May 06, 2005
Bug(s): #90539
ID: 200505-03

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: net-analyzer/ethereal
Vulnerable: < 0.10.11
Unaffected: >= 0.10.11
Architectures: All supported architectures


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, 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 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 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.


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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.11"
