Detailsinfo

A vulnerability classified as critical has been found in rdesktop 1.5.0. Affected is the function (rdp.c) of the file rdp.c of the component Remote Desktop Protocol. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Buffer overflow in the process_redirect_pdu (rdp.c) function in rdesktop 1.5.0 allows remote attackers to execute arbitrary code via a Remote Desktop Protocol (RDP) redirect request with modified length fields.

The bug was discovered 05/07/2008. The weakness was published 05/12/2008 with iDEFENSE (Website). The advisory is shared for download at xforce.iss.net.
