Trustix Secure Linux Security Advisory #2005-0070
Package names: kernel, perl
Summary: Multiple vulnerabilities
Date: 2005-12-09
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.
perl
Perl is a high-level programming language with roots in C, sed, awk and
shell scripting. Perl is good at handling processes and files, and is
especially good at handling text. Perl's hallmarks are practicality and
efficiency. While it is used to do a lot of different things, Perl's
most common applications (and what it excels at) are probably system
administration utilities and web programming. A large proportion of the
CGI scripts on the web are written in Perl. You need the perl package
installed on your system so that your system can handle Perl scripts.
Problem description:
kernel < TSL 3.0 >
- New Upstream.
- SECURITY Fix: Memory leak in the VFS file lease handling in locks.c
allows local users to cause a denial of service via certain Samba
activities that cause an fasync entry to be re-allocated by the
fcntl_setlease function after the fasync queue has already been
cleaned by the locks_delete_lock function.
- The auto-reap of child processes in Linux kernel 2.6 includes
processes with ptrace attached, which leads to a dangling ptrace
reference and allows local users to cause a denial of service (crash).
- The time_out_leases function in locks.c allows local users to cause a
denial of service (kernel log message consumption) by causing a large
number of broken leases, which is recorded to the log using the printk
function.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the names CVE-2005-3807, CVE-2005-3784 and CVE-2005-3857 to
these issues.
perl < TSL 3.0 > < TSL 2.2 > < TSEL 2 >
- SECURITY Fix: Integer overflow in the format string functionality
(Perl_sv_vcatpvfn) allows attackers to overwrite arbitrary memory and
possibly execute arbitrary code via format string specifiers with
large values.
The Common Vulnerabilities and Exposures project has assigned the
name CVE-2005-3962 to this issue.
Action:
We recommend that all systems with this package installed be upgraded.
