Trustix Secure Linux Security Advisory #2006-0051
Package names: bind, kernel, openssl
Summary: Multiple vulnerabilities
Date: 2006-09-15
Affected versions: Trustix Secure Linux 2.2
Trustix Secure Linux 3.0
Trustix Operating System - Enterprise Server 2
- --------------------------------------------------------------------------
Package description:
bind
BIND (Berkeley Internet Name Domain) is an implementation of the DNS
(Domain Name System) protocols. BIND includes a DNS server (named),
which resolves host names to IP addresses, and a resolver library
(routines for applications to use when interfacing with DNS). A DNS
server allows clients to name resources or objects and share the
information with other network machines. The named DNS server can be
used on workstations as a caching name server, but is generally only
needed on one machine for an entire network.
kernel
The kernel package contains the Linux kernel (vmlinuz), the core of
your Trustix Secure Linux operating system. The kernel handles the
basic functions of the operating system: memory allocation, process
allocation, device input and output, etc.
openssl
A C library that provides various crytographic algorithms and
protocols including DES, RC4, RSA, and SSL. Includes shared libraries.
Problem description:
bind < TSL 3.0 > < TSL 2.2 > < TSEL 2 >
- New Upstream.
- SECURITY Fix: Some vulnerabilities have been reported in BIND,
which can be exploited by malicious people to cause a DoS.
- Fix an assertion error within the processing of SIG queries that
can be exploited to crash either a recursive server when more than
one SIG(covered) Resource Record set (RRset) is returned or an
authoritative server serving a RFC 2535 DNSSEC zone where there
are multiple SIG(covered) RRsets.
- Fix an error within the handling of multiple recursive queries that
can be exploited to trigger an INSIST failure by causing the response
to the query to arrive after all clients looking for the response
have left the recursion queue.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the names CVE-2006-4095 and CVE-2006-4096 to these issues.
kernel < TSL 2.2 >
- New Upstream.
- SECURITY Fix: Fix possible UDF deadlock and memory corruption.
- McAfee Avert Labs has reported a vulnerability in the Linux Kernel,
which can be exploited by malicious, local users to gain escalated
privileges. The vulnerability is caused due to an error in the SCTP
module within the "sctp_make_abort_user()" function and can be
exploited to execute arbitrary code with escalated privileges.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the names CVE-2006-4145 and CVE-2006-3745 to these
issues.
- Also includes fixes for CVE-2006-0039, CVE-2006-1857, CVE-2006-1858,
CVE-2006-1864, CVE-2006-2271, CVE-2006-2272, CVE-2006-1525,
CVE-2006-2274, CVE-2006-1524, CVE-2005-3180, CVE-2005-2709,
CVE-2005-2708, CVE-2005-2490, CVE-2006-1528 and CVE-2006-4093.
openssl < TSL 3.0 > < TSL 2.2 > < TSEL 2 >
- New Upstream.
- SECURITY FIX: A vulnerability has been identified which could be
exploited by attackers to bypass security restrictions. This flaw is
due to an error when handling and verifying RSA keys with exponent 3,
which could be exploited by attackers to forge PKCS #1 v1.5
signatures and bypass security verifications.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2006-4339.
