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

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"

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

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"
