Trustix Secure Linux Security Advisory #2006-0006
Package names: fcron, kernel, unzip
Summary: Multiple vulnerabilities
Date: 2006-02-10
Affected versions: Trustix Secure Linux 2.2
Trustix Secure Linux 3.0
Trustix Operating System - Enterprise Server 2
- --------------------------------------------------------------------------
Package description:
fcron
Fcron is a scheduler. It aims at replacing Vixie Cron, so it implements most
of its functionalities.
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.
unzip
The unzip utility is used to list, test, or extract files from a zip
archive. Zip archives are commonly found on MS-DOS systems. The zip
utility, included in the zip package, creates zip archives. Zip and
unzip are both compatible with archives created by PKWARE(R)'s PKZIP
for MS-DOS, but the programs' options and default behaviors do differ
in some respects.
Problem description:
fcron < TSL 3.0 > < TSL 2.2 > < TSEL 2 >
- SECURITY Fix: Adam Zabrocki and Karol Wiesek has reported vulnerabilities
in fcron, which can be exploited by malicious, local users to gain
escalated privileges. The issue exits in convert-fcrontab when handling
an overly long username supplied via the command line and due to missing
validation of username. (SA18719)
kernel < TSL 3.0 > < TSL 2.2 > < TSEL 2 >
- SECURITY Fix: Linux kernel before 2.6.15.3 down to 2.6.12, while
constructing an ICMP response, does not properly handle when the
ip_options_echo function in icmp.c fails, which allows remote attackers
to cause a denial of service (crash) via vectors such as (1) record-route
and (2) timestamp IP options with the needaddr bit set and a truncated
value.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2006-0454 to this issue.
- SECURITY Fix: Linus Torvalds: Fix outstanding gzip/zlib security issues.
- SECURITY Fix: Disallows local users to write to privileged IO ports
via OUTS instruction isofs driver ignore parameters.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2005-0204 to this issue.
unzip < TSL 3.0 > < TSL 2.2 >
- SECURITY Fix: Fixes Buffer overflow vulnerability which allows local
users to execute arbitrary code via a long filename command line argument.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2005-4667 to this issue.
