▸ GLSA 200806-04 rdesktop: Multiple vulnerabilities this version unaffected normal remote 2008-06-14

Multiple vulnerabilities in rdesktop may lead to the execution of arbitrary code or a Denial of Service.

Announced: 2008-06-14
Revised: 2008-06-14
Access: remote
Bugs: #220911
Advisory: https://security.gentoo.org/glsa/200806-04

Affected packages

Package	Arch	Vulnerable	Unaffected
net-misc/rdesktop	*	< 1.6.0	>= 1.6.0

Background

rdesktop is an open source Remote Desktop Protocol (RDP) client.

Description

An anonymous researcher reported multiple vulnerabilities in rdesktop via iDefense Labs:

An integer underflow error exists in the function iso_recv_msg() in the file iso.c which can be triggered via a specially crafted RDP request, causing a heap-based buffer overflow (CVE-2008-1801).
An input validation error exists in the function process_redirect_pdu() in the file rdp.c which can be triggered via a specially crafted RDP redirect request, causing a BSS-based buffer overflow (CVE-2008-1802).
An integer signedness error exists in the function xrealloc() in the file rdesktop.c which can be be exploited to cause a heap-based buffer overflow (CVE-2008-1803).

Impact

An attacker could exploit these vulnerabilities by enticing a user to connect to a malicious RDP server thereby allowing the attacker to execute arbitrary code or cause a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All rdesktop users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/rdesktop-1.6.0"
