Gentoo Linux Security Advisory GLSA 200408-14
Severity: Normal
Title: acroread: UUDecode filename buffer overflow
Date: August 15, 2004
Bugs: #60205
ID: 200408-14
Synopsis
acroread contains two errors in the handling of UUEncoded
filenames that may lead to execution of arbitrary code or
programs.
Background
acroread is Adobe’s Acrobat PDF reader for Linux.
Affected packages
Package | Vulnerable | Unaffected |
1 app-text/acroread | <= 5.08 | >= 5.09 |
Description
acroread contains two errors in the handling of UUEncoded
filenames. First, it fails to check the length of a filename before
copying it into a fixed size buffer and, secondly, it fails to
check for the backtick shell metacharacter in the filename before
executing a command with a shell.
Impact
By enticing a user to open a PDF with a specially crafted
filename, an attacker could execute arbitrary code or programs with
the permissions of the user running acroread.
Workaround
There is no known workaround at this time. All users are
encouraged to upgrade to the latest available version of
acroread.
Resolution
All acroread users should upgrade to the latest version:
# emerge sync # emerge -pv ">=app-text/acroread-5.09" # emerge ">=app-text/acroread-5.09"

Gentoo Linux Security Advisory GLSA 200408-15
Severity: Normal
Title: Tomcat: Insecure Installation
Date: August 15, 2004
Bugs: #59232
ID: 200408-15
Synopsis
Improper file ownership may allow a member of the tomcat group
to execute scripts as root.
Background
Tomcat is the Apache Jakarta Project’s official implementation
of Java Servlets and Java Server Pages.
Affected packages
Package | Vulnerable | Unaffected |
1 net-www/tomcat | < 5.0.27-r3 | >= 5.0.27-r3 *>= 4.1.30-r4 *>= 3.3.2-r2 |
Description
The Gentoo ebuild for Tomcat sets the ownership of the Tomcat
init scripts as tomcat:tomcat, but those scripts are executed with
root privileges when the system is started. This may allow a member
of the tomcat group to run arbitrary code with root privileges when
the Tomcat init scripts are run.
Impact
This could lead to a local privilege escalation or root
compromise by authenticated users.
Workaround
Users may change the ownership of /etc/init.d/tomcat* and
/etc/conf.d/tomcat* to be root:root:
# chown -R root:root /etc/init.d/tomcat* # chown -R root:root
/etc/conf.d/tomcat*
Resolution
All Tomcat users can upgrade to the latest stable version, or
simply apply the workaround:
# emerge sync # emerge -pv ">=net-www/tomcat-5.0.27-r3" # emerge ">=net-www/tomcat-5.0.27-r3"
