Test ID:1.3.6.1.4.1.25623.1.0.55020
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-162-1 (ekg)
Summary:Ubuntu USN-162-1 (ekg)
Description:
The remote host is missing an update to ekg
announced via advisory USN-162-1.

A security issue affects the following Ubuntu releases:

Ubuntu 5.04 (Hoary Hedgehog)

The following packages are affected: ekg libgadu3

Marcin Owsiany and Wojtek Kaniewski discovered that some contributed
scripts (contrib/ekgh, contrib/ekgnv.sh, and contrib/getekg.sh) in the
ekg package created temporary files in an insecure way, which allowed
exploitation of a race condition to create or overwrite files with the
privileges of the user invoking the script. (CVE-2005-1850)

Marcin Owsiany and Wojtek Kaniewski discovered a shell command
injection vulnerability in a contributed utility
(contrib/scripts/ekgbot-pre1.py). By sending specially crafted content
to the bot, an attacker could exploit this to execute arbitrary code
with the privileges of the user running ekgbot. (CVE-2005-1851)

Marcin Ślusarz discovered an integer overflow in the Gadu library. By
sending a specially crafted incoming message, a remote attacker could
execute arbitrary code with the privileges of the application using
libgadu. (CVE-2005-1852)

Eric Romang discovered that another contributed script
(contrib/scripts/linki.py) created temporary files in an insecure way,
which allowed exploitation of a race condition to create or overwrite
files with the privileges of the user invoking the script.
(CVE-2005-1916)

Grzegorz Jaśkiewicz discovered several integer overflows in the Gadu
library. A remote attacker could exploit this to crash the Gadu client
application or even execute arbitrary code with the privileges of the
user by sending specially crafted messages. (CVE-2005-2369)

Szymon Zygmunt and Michał Bartoszkiewicz discovered a memory alignment
error in the Gadu library. By sending specially crafted messages, a
remote attacker could crash the application using the library.
(CVE-2005-2370)

Marcin Ślusarz discovered that the Gadu library did not properly
handle endianess conversion in some cases. This caused invalid
behavior on big endian architectures. The only affected supported
architecture is powerpc. (CVE-2005-2448)

Solution:
The problem can be corrected by upgrading the affected package to
version 1:1.5-4ubuntu1.2. In general, a standard system upgrade is
sufficient to effect the necessary changes. If you use the Instant
Messaging application Kopete, you need to restart it after the
upgrade since it uses the libgadu3 library package.
