Trustix Secure Linux Security Advisory #2006-0018
Package names: kernel, samba
Summary: Multiple vulnerabilities
Date: 2006-04-04
Affected versions: Trustix Secure Linux 2.2
Trustix Secure Linux 3.0
Trustix Operating System - Enterprise Server 2
- --------------------------------------------------------------------------
Package description:
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.
samba
Samba provides an SMB server which can be used to provide network
services to SMB (sometimes called "Lan Manager") clients, including
various versions of MS Windows, OS/2, and other Linux machines. Samba
uses NetBIOS over TCP/IP (NetBT) protocols and does NOT need NetBEUI
(Microsoft Raw NetBIOS frame) protocol.
Problem description:
kernel < TSL 3.0 >
- New Upstream.
- SECURITY Fix: Marco Ivaldi has reported a weakness caused due
to an error within the "ip_push_pending_frames()" function when
creating a packet in reply to a received SYN/ACK packet. This
causes RST packets to be sent with a IP ID value that is
incremented per packet. This can potentially be exploited to
conduct idle scan attacks.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2006-1242 to this issue.
samba < TSL 3.0 > < TSL 2.2 > < TSEL 2 >
- New Upstream
- SECURITY Fix: The winbindd daemon included in previous Samba
version writes the clear text of server's machine credentials
to its log file at level 5. The winbindd log files are world
readable by default and often log files are requested on open
mailing lists as tools used to debug server misconfigurations.
This affects servers configured to use domain or ads security
and possibly Samba domain controllers as well (if configured
to use winbindd).
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2006-1059 to this issue.
Action:
We recommend that all systems with this package installed be upgraded.
