freerdp: FreeRDP: Denial of Service via double free vulnerability during disconnect

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. This double free vulnerability occurs during the cleanup process when a remote desktop session disconnects. Specifically, if a title allocation fails, a pointer to an application window is freed but not removed fro...

freerdp: FreeRDP: Denial of Service via crafted audio data in RDP

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. A remote attacker can exploit a sizet underflow vulnerability in the IMA-ADPCM and MS-ADPCM audio decoders by sending specially crafted audio data over the RDPSND audio channel. This underflow leads to a...

FreeRDP: FreeRDP: Information disclosure via heap memory out of bounds read

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A remote attacker could exploit a vulnerability where pixel data from adjacent heap memory is rendered to the screen. This can lead to the disclosure of sensitive data to the attacker...

freerdp: FreeRDP: Denial of service due to use-after-free vulnerability

A flaw was found in FreeRDP. A remote attacker could exploit a use-after-free vulnerability in the xfSetWindowMinMaxInfo function. This occurs when a freed window pointer is dereferenced because the main thread concurrently deletes a window while the Remote Desktop Protocol RAIL channel thread is...

freerdp: FreeRDP has a heap-buffer-overflow in bitmap_cache_put via OOB cacheId

A heap based buffer overflow flaw has been discovered in FreeRDP. This client-side heap out-of-bounds read/write occurs in FreeRDP's bitmap cache subsystem due to an off-by-one boundary check in bitmapcacheput. A malicious server can send a CACHEBITMAPORDER Rev1 with cacheId equal to maxCells,...

freerdp: FreeRDP has an out-of-bounds read in ADPCM decoders due to missing predictor/step_index bounds checks

An out of bounds read flaw has been discovered in FreeRDP. This out-of-bounds read exists in the MS-ADPCM and IMA-ADPCM decoders due to unchecked predictor and stepindex values from input data. An attacker may be able to leverage this weakness to leak global data...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol. Clients that use FreeRDP versions prior to 3.5.0 or 2.11.6 and have connections to servers using the NSC codec are vulnerable to integer underflow. Versions 3.5.0 and 2.11.6 address this issue. As a workaround, do not use the NSC...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol. Clients that use the /bpp:32 legacy GDI drawing path with a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read vulnerabilities. Versions 3.5.0 and 2.11.6 address this issue. As a workaround, use modern...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free remote desktop protocol library and client. Versions of FreeRDP that are affected may attempt integer additions on too narrow types, resulting in the allocation of a buffer that is too small to hold the written data. A malicious server can trick a FreeRDP-based client into readi...

FreeRDP is a free implementation of the Remote Desktop Protocol. Clients that use versions of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read vulnerabilities. Versions 3.5.0 and 2.11.6 address this issue. As a workaround, deactivate /gfx which is enabled by default; instead,...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free remote desktop protocol library and clients. Affected versions of FreeRDP lack input length validation in the urbdrc channel. A malicious server can trick a FreeRDP-based client into reading out-of-bound data and sending it back to the server. This issue has been addressed in...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol RDP, released under the Apache license. All FreeRDP clients prior to version 2.4.1 that used gateway connections /gt:rpc failed to validate input data. A malicious gateway could allow client memory to be written out of bounds. This...
