FreeRDP Use-After-Free in RDPGFX_CMDID_RESETGRAPHICS
Résumé
FreeRDP Use-After-Free in RDPGFX_CMDID_RESETGRAPHICS
Description d'origine
La description telle que publiée par la source (souvent en anglais).
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Versions of FreeRDP on the 3.x release branch before beta3 are subject to a Use-After-Free in processing RDPGFX_CMDID_RESETGRAPHICS packets. If context->maxPlaneSize is 0, context->planesBuffer will be freed. However, without updating context->planesBuffer, this leads to a Use-After-Free exploit vector. In most environments this should only result in a crash. This issue has been addressed in version 3.0.0-beta3 and users of the beta 3.x releases are advised to upgrade. There are no known workarounds for this vulnerability.
