FreeRDP FreeRDP 2.0.0-rc3 released version before commit 205c612820dac644d665b5bb1cdf437dc5ca01e3 contains a Other/Unknown vulnerability in channels/drdynvc/client/drdynvc_main.c, drdynvc_process_capability_request that can result in The RDP server can read the client's memory.. This attack appear to be exploitable via RDPClient must connect the rdp server with echo option. This vulnerability appears to have been fixed in after commit 205c612820dac644d665b5bb1cdf437dc5ca01e3. FreeRDP 2.0.0-rc3, en versiones anteriores al commit con ID 205c612820dac644d665b5bb1cdf437dc5ca01e3, contiene una vulnerabilidad desconocida en channels/drdynvc/client/drdynvc_main.c, drdynvc_process_capability_request que puede resultar en que el servidor RDP sea capaz de leer la memoria del cliente. El cliente debe conectarse al servidor RDP con la opción "echo". • https://access.redhat.com/errata/RHSA-2019:2157 https://github.com/FreeRDP/FreeRDP/issues/4866 https://github.com/FreeRDP/FreeRDP/pull/4871 https://github.com/FreeRDP/FreeRDP/pull/4871/commits/baee520e3dd9be6511c45a14c5f5e77784de1471 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YVJKO2DR5EY4C4QZOP7SNNBEW2JW6FHX https://usn.ubuntu.com/4379-1 https://access.redhat.com/security/cve/CVE-2018-1000852 https://bugzilla.redhat.com/show_bug.cgi?id=1661640 • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2018-8786
FreeRDP prior to version 2.0.0-rc4 contains an Integer Truncation that leads to a Heap-Based Buffer Overflow in function update_read_bitmap_update() and results in a memory corruption and probably even a remote code execution. FreeRDP en versiones anteriores a la 2.0.0-rc4 contiene un truncamiento de enteros que conduce a un desbordamiento de búfer basado en memoria dinámica (heap) en la función zgfx_decompress() y que resulta en una corrupción de memoria y, probablemente, incluso en la ejecución remota de código. A flaw was found in freerdp in versions prior to version 2.0.0-rc4. An integer truncation that leads to a heap-based buffer overflow in the update_read_bitmap_update() function results in a memory corruption. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • http://www.securityfocus.com/bid/106938 https://access.redhat.com/errata/RHSA-2019:0697 https://github.com/FreeRDP/FreeRDP/commit/445a5a42c500ceb80f8fa7f2c11f3682538033f3 https://lists.debian.org/debian-lts-announce/2019/02/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YVJKO2DR5EY4C4QZOP7SNNBEW2JW6FHX https://research.checkpoint.com/reverse-rdp-attack-code-execution-on-rdp-clients https://usn.ubuntu.com/3845-1 https://usn.ubuntu.com/3845-2 https:/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-680: Integer Overflow to Buffer Overflow CWE-681: Incorrect Conversion between Numeric Types CWE-787: Out-of-bounds Write •
