Detail
Problem Description: An updated rdesktop package that fixes one security issue is now available for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 3. Description: rdesktop is a client for the Remote Desktop Server (previously, Terminal Server) in Microsoft Windows. It uses the Remote Desktop Protocol (RDP) to remotely present a user's desktop. A directory traversal flaw was found in the way rdesktop shared a local path with a remote server. If a user connects to a malicious server with rdesktop, the server could use this flaw to cause rdesktop to read and write to arbitrary, local files accessible to the user running rdesktop. (CVE-2011-1595) Red Hat would like to thank Cendio AB for reporting this issue. Cendio AB acknowledges an anonymous contributor working with the SecuriTeam Secure Disclosure program as the original reporter. Users of rdesktop should upgrade to this updated package, which contains a backported patch to resolve this issue. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259 5.

72301 | rdesktop Disk Redirection Traversal Arbitrary File Manipulation rdesktop contains a flaw that allows a remote attacker to traverse outside of a restricted path. The issue is due to the disk redirection feature not properly sanitizing user input, specifically directory traversal style attacks (e.g., ../../). This directory traversal attack would allow the attacker to manipulate arbitrary files. |
