CVE-2026-109947
FreeRDP from 3.20.1 before 3.32.0 contains an uncontrolled resource allocation vulnerability that allows malicious RDP servers to exhaust client memory via oversized drive redirection read requests. Attackers can send IRPMJREAD with Length 0xffffffff, causing roughly 4 GiB of zeroed allocation on...
CVE-2026-109945
FreeRDP 3.0.0 before 3.32.0 contains a heap use-after-free vulnerability in smartcard emulation when SCARDIOCTLDISCONNECT and SCARDIOCTLTRANSMIT operate concurrently on one card handle. A malicious RDP server can overlap these IRPs through separate context workers to free and reuse the SCardHandl...
CVE-2026-109946
FreeRDP 3.11.0 before 3.32.0 does not validate that AVC444 and AVC444v2 region widths are even before YUV444 conversion, so an odd width reaches an assertion and aborts the client. A malicious or compromised RDP server can terminate a connected FreeRDP client after RDPGFX AVC444 negotiation by...
CVE-2026-109944
FreeRDP 3.0.0 before 3.32.0 does not remove card handles when EmulateSCardReleaseContext releases a smartcard-emulation context, so EmulateSCardTransmit later looks up the deleted parent context and reaches a terminating WINPRASSERT. A malicious RDP server can crash a connecting client with...
CVE-2026-109943
FreeRDP 3.29.0 before 3.32.0 contains a double free in the client's async-update message proxy, which shallow-copies the parser-owned PolygonSC or PolygonCB points array when numPoints is zero, so both the queue consumer and parser cleanup free it. A malicious RDP server can send a point-bearing...
CVE-2026-109942
FreeRDP 2.3.0 before 3.32.0 dereferences a NULL stream in rdgprocessclosepacket in libfreerdp/core/gateway/rdg.c because rdgprocesscontrolpacket accepts a header-only PKTTYPECLOSECHANNEL packet and passes the null payload without a check. A malicious or compromised RD Gateway can send an eight-by...
EUVD-2026-98705
FreeRDP 3.0.0-beta1 before 3.32.0 on Unix builds with PKCS11 support has a stack-based buffer overflow in wprintKeyName in WinPR's NCrypt PKCS11 provider. It hex-encodes a key's CKAID, which can be up to 64 bytes, into a fixed 128-byte stack buffer. An attacker supplying a malicious PKCS11 token ...
CVE-2026-109940
FreeRDP 3.0.0-beta1 before 3.32.0 on Unix builds with PKCS11 support has a stack-based buffer overflow in wprintKeyName in WinPR's NCrypt PKCS11 provider. It hex-encodes a key's CKAID, which can be up to 64 bytes, into a fixed 128-byte stack buffer. An attacker supplying a malicious PKCS11 token ...
CVE-2026-109940
FreeRDP version 3.0.0-beta1 before 3.32.0 on Unix builds with PKCS#11 support is vulnerable to a stack-based buffer overflow . The issue resides in the wprintKeyName() function within WinPR's NCrypt PKCS#11 provider, where a key's CKA_ID (up to 64 bytes) is hex-encoded into a fixed 128-byte stack...
CVE-2026-109941
FreeRDP from 2.3.0 before 3.32.0 contains an infinite loop vulnerability in httpchunckedread that allows malicious RD Gateways to hang clients by sending incomplete chunked responses. Attackers can send a partial chunk-size line or footer followed by a clean TLS shutdown, causing zero-byte reads ...
CVE-2026-109940

It hex-encodes a key's CKAID, which can be up to 64 bytes, into a fixed 128-byte stack buffer. An attacker supplying a malicious PKCS11 token ...
CVE-2026-109939
FreeRDP 3.27.1 before 3.32.0 contains a NULL pointer dereference in updatereadcachebitmapv3order in libfreerdp/core/orders.c, which accesses the client bitmap cache when the CBR3DONOTCACHE flag is set, even though the cache is not yet initialized before Demand Active. A malicious or compromised R...
CVE-2026-109680
FreeRDP 3.18.0 before 3.32.0 has a heap-based out-of-bounds write in freerdpinterruptiblegetline, which shrinks the buffer to 32 bytes while keeping a pre-filled suggested username's length as its write offset. A malicious or compromised ARM routing service can return a long redirectedUsername th...
CVE-2026-109938
Positive mapped-video coordinates overflow and abort FreeRDP clients A malicious or compromised RDP server can terminate a FreeRDP client after the user connects with video redirection enabled...
CVE-2026-109679
FreeRDP 3.0.0-beta4 before 3.32.0 contains a NULL pointer dereference in armhandlerequestok when an ARM endpoint returns an empty HTTP 200 body. Attackers controlling the configured ARM gateway can return a zero-length body to pass NULL to strnlen and crash the connecting client...
openssh: openssh: a compressed payload can expand past the maximum packet size
A flaw was found in OpenSSH. After compression is negotiated, a compressed payload can expand past the maximum supported packet size because the inflate loop does not stop at that limit. Memory use grows in the process handling that connection...
openssh: openssh: '$' and '\' in a command-line username expand through %u
A flaw was found in OpenSSH. A username entered on the ssh command line can still contain '$' or a non-trailing backslash. When a configuration expands %u inside ProxyCommand or Match exec, those characters are passed into the shell...
openssh: openssh: shared LZ77 compression dictionary leaks plaintext across channels
A flaw was found in OpenSSH. When compression is negotiated, channels on the same connection share one LZ77 dictionary. A peer who can write on one channel can recover plaintext from another channel by chosen-plaintext lengths...
openssh: openssh: sftp can write outside the destination directory from a server-supplied path
A flaw was found in OpenSSH. During an sftp copy, a malicious server can supply an empty name, a slash-only path, or a ".." basename that sftp uses as the local destination, writing outside the directory the user selected...
