Gentoo: GLSA-200406-01: Ethereal: Multiple security problems
Summary
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Gentoo Linux Security Advisory GLSA 200406-01 https://security.gentoo.org/
Severity: High Title: Ethereal: Multiple security problems Date: June 04, 2004 Bugs: #51022 ID: 200406-01
Synopsis ======= Multiple vulnerabilities including one buffer overflow exist in Ethereal, which may allow an attacker to run arbitrary code or crash the program.
Background ========= Ethereal is a feature rich network protocol analyzer.
Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/ethereal <= 0.10.3 >= 0.10.4
========== There are multiple vulnerabilities in versions of Ethereal earlier than 0.10.4, including:
* A buffer overflow in the MMSE dissector.
* Under specific conditions a SIP packet could make Ethereal crash.
* The AIM dissector could throw an assertion, causing Ethereal to crash.
* The SPNEGO dissector could dereference a null pointer, causing a crash.
Impact ===== An attacker could use these vulnerabilities to crash Ethereal 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 release.
Resolution ========= All Ethereal users should upgrade to the latest stable version:
# emerge sync
# emerge -pv ">=net-analyzer/ethereal-0.10.4" # emerge ">=net-analyzer/ethereal-0.10.4"
