freerdp: FreeRDP has a heap-buffer-overflow in urb_select_interface

A heap buffer overflow has been discovered in FreeRDP. The URBDRC client uses server-supplied interface numbers as array indices without bounds checks, causing an out-of-bounds read in libusbudevselectinterface...

freerdp: FreeRDP heap-buffer-overflow

A heap based buffer overflow has been discovered in FreeRDP. In affected versions the URBDRC client does not perform bounds checking on server‑supplied MSUSBINTERFACEDESCRIPTOR values and uses them as indices in libusbudevcompletemsconfigsetup, causing an out‑of‑bounds read...

freerdp: FreeRDP: Arbitrary code execution via heap buffer overflow in GDI surface pipeline

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. A malicious RDP server can exploit a heap buffer overflow vulnerability by sending a specially crafted graphics command to a FreeRDP client. This allows the server to write data outside of its intended memory...

freerdp: FreeRDP: Denial of Service via use-after-free in AUDIN format renegotiation

A use after free flaw was found in FreeRDP. AUDIN format renegotiation frees the active format list while the capture thread continues using audin-format, leading to a use after free in audioformatcompatible. A malicious server can trigger a client‑side heap use after free causing a crash...
