freerdp: FreeRDP: Denial of Service via FastGlyph parsing buffer overflow

A flaw was found in FreeRDP. A malicious server can exploit a vulnerability in FastGlyph parsing, which improperly trusts data length without sufficient validation. This can lead to a client-side global buffer overflow, resulting in a denial of service DoS due to a crash. For this vulnerability t...

freerdp: FreeRDP heap-buffer-overflow

A heap based buffer overflow has been discovered in FreeRDP. This heap-buffer-overflow occurs in drive read when a server-controlled read length is used to read file data into an IRP output stream buffer without a hard upper bound, allowing an oversized read to overwrite heap memory...

freerdp: FreeRDP has a Heap-use-after-free in play_thread

A heap use after free has been discovered in FreeRDP. The RDPSND async playback thread can process queued PDUs after the channel is closed and internal state is freed, leading to a use after free in rdpsndtreatwave...

freerdp: FreeRDP has a Heap-use-after-free in urb_select_interface

A heap buffer use after free has been discovered in FreeRDP. urbselectinterface can free the device's MS config on error but later code still dereferences it, leading to a use after free in libusbudevselectinterface...

freerdp: FreeRDP has a heap-use-after-free in video_timer

A use after free flaw has been discovered in FreeRDP. The videotimer can send client notifications after the control channel is closed, dereferencing a freed callback and triggering a use after free. A malicious server can trigger a client‑side heap use after free causing a crash DoS...

freerdp: FreeRDP heap-buffer-overflow

A heap based buffer overflow has been discovered in FreeRDP. Prior to 3.20.1, a malicious RDP server can trigger a heap-buffer-overflow write in the FreeRDP client when processing Audio Input AUDIN format lists. audinprocessformats reuses callback-formatscount across multiple MSGSNDINFORMATS PDUs...

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...

freerdp: FreeRDP heap-use-after-free

A heap use after free flaw has been discovered in FreeRDP. A race in the serial channel IRP thread tracking allows a heap use‑after‑free when one thread removes an entry from serial-IrpThreads while another reads it...
