The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-109824 advisory. FreeRDP before 3.29.0 contains a client-side heap use-after-free in the async update message proxy for WINDOWICONORDER when AsyncUpdate is enabled e.g. xfreerdp...

CVE-2026-91962

A flaw was found in FreeRDP. An integer overflow in the audin Apple backends, specifically when processing FramesPerPacket values from MSGSNDINOPEN messages, allows a malicious RDP Remote Desktop Protocol server to supply crafted values. This can cause the AudioQueueAllocateBuffer size computatio...

CVE-2026-91956

A flaw was found in FreeRDP. A malicious Remote Desktop Protocol RDP server can exploit an out-of-bounds read vulnerability in the URBDRC USB device redirection channel. By sending a specially crafted message, the server can cause the FreeRDP client to read beyond its allocated memory, leading to...

CVE-2026-91954

A flaw was found in FreeRDP. A malicious Remote Desktop Protocol RDP server can trigger a null pointer dereference in the gdisurfacebits function by sending a specially crafted Surface Bits command that claims to use the NSCodec codec ID. This vulnerability exists even when the NSCodec is disable...

CVE-2026-91952

A flaw was found in FreeRDP. A malicious Remote Desktop Protocol RDP server can send specially crafted AVC444 graphics updates. This can cause the pooldecoderect function to enter an infinite loop when decoding AVC444 metablocks with an excessive number of region rectangles. The vulnerability lea...

CVE-2026-91964

A flaw was found in FreeRDP. A malicious Remote Desktop Protocol RDP server can exploit a heap-based buffer overflow vulnerability in the negosendnegotiationrequest function. By sending a specially crafted Server Redirection PDU message with an attacker-controlled LoadBalanceInfo field, the serve...

CVE-2026-91963

A flaw was found in FreeRDP. An uninitialized heap memory disclosure vulnerability exists in the urbdrc USB redirection channel. A malicious Remote Desktop Protocol RDP server can exploit this by inducing failing USB transfers, allowing it to read uninitialized heap memory from the client. This...

DEBIAN-CVE-2026-91953

FreeRDP versions before 3.31.0 contain a heap buffer overflow vulnerability in negosendnegotiationrequest that fails to validate the LBLOADBALANCEINFO field length before writing to a fixed 512-byte buffer. A malicious RDP server or man-in-the-middle can send a Server Redirection PDU with an...

EUVD-2026-78640

FreeRDP versions before 3.31.0 contain a heap-based buffer overflow in negosendnegotiationrequest when processing Server Redirection PDU messages with attacker-controlled LoadBalanceInfo fields. A malicious RDP server can trigger the overflow by sending an arbitrary-length field that gets written...

CVE-2026-91961 FreeRDP before 3.31.0 Denial of Service via URBDRC

FreeRDP before 3.31.0 contains a denial-of-service vulnerability in the URBDRC control-transfer request path that fails to validate OutputBufferSize before forwarding to the libusb backend. A malicious RDP server can send a control-transfer request with OutputBufferSize set to 65536, triggering a...

CVE-2026-91956 FreeRDP before 3.31.0 Out-of-Bounds Read via URBDRC

FreeRDP before 3.31.0 contains an out-of-bounds read vulnerability in the URBDRC channel's funcgetepdesc function that indexes interface arrays by position instead of protocol field InterfaceNumber. A malicious RDP server can send a crafted SELECTCONFIGURATION message with permuted InterfaceNumbe...

CVE-2026-91954

FreeRDP versions before 3.31.0 contain a null pointer dereference in the gdi_surface_bits function. A malicious RDP server can crash a FreeRDP client by sending a crafted Surface Bits command that claims to use the NSCodec codec ID, even when the codec is disabled on the client side. The impact i...

EUVD-2026-78809

FreeRDP versions before 3.31.0 contain an infinite-loop denial of service in the pooldecoderect function when decoding AVC444 metablocks with more region rectangles than preallocated worker array size. A malicious RDP server can send crafted AVC444 graphics updates causing the threaded decode pat...

CVE-2026-91953 FreeRDP before 3.31.0 Heap Buffer Overflow via LB_LOAD_BALANCE_INFO

FreeRDP versions before 3.31.0 contain a heap buffer overflow vulnerability in negosendnegotiationrequest that fails to validate the LBLOADBALANCEINFO field length before writing to a fixed 512-byte buffer. A malicious RDP server or man-in-the-middle can send a Server Redirection PDU with an...
