Date:	04/13/2005
Bugs:	#88904
ID:	200504-10

Synopsis

Gld contains several serious vulnerabilities, potentially resulting in the execution of arbitrary code as the root user.

Background

Gld is a standalone greylisting server for Postfix.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
mail-filter/gld	<= 1.4	>= 1.5	All supported architectures

Description

dong-hun discovered several buffer overflows in server.c, as well as several format string vulnerabilities in cnf.c.

Impact

An attacker could exploit this vulnerability to execute arbitrary code with the permissions of the user running Gld, the default user being root.

Workaround

There is no known workaround at this time.

Resolution
