CVE-2026-33977

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. A malicious RDP server can exploit this vulnerability by sending specially crafted audio data in IMA ADPCM format with an invalid initial step index value. This unvalidated input can cause the FreeRDP client to...

CVE-2026-33995

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A remote attacker could exploit a double-free vulnerability in the Kerberos security context functions, specifically kerberosAcceptSecurityContext and kerberosInitializeSecurityContextA, within the WinPR library...

CVE-2026-33984

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A remote attacker could exploit a heap buffer overflow vulnerability in the resizevbarentry function. This occurs when an error in buffer resizing leads to attacker-controlled pixel data being written into an...

CVE-2026-33983

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. A remote attacker could exploit this vulnerability by sending a specially crafted RDP message. This can lead to an undefined behavior where a wrapped value is used as a shift exponent, causing an approximately ...

CVE-2026-33995

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, a double-free vulnerability in kerberosAcceptSecurityContext and kerberosInitializeSecurityContextA WinPR, winpr/libwinpr/sspi/Kerberos/kerberos.c can cause a crash in any FreeRDP clients on systems where...

CVE-2026-33987

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, in persistentcachereadentryv3 in libfreerdp/cache/persistent.c, persistent-bmpSize is updated before winpralignedrecalloc. If realloc fails, bmpSize is inflated while bmpData points to the old buffer. This...

CVE-2026-33984

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, in resizevbarentry in libfreerdp/codec/clear.c, vBarEntry-size is updated to vBarEntry-count before the winpralignedrecalloc call. If realloc fails, size is inflated while pixels still points to the old,...

CVE-2026-33983

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, progressivedecompresstileupgrade detects a mismatch via progressiverfxquantcmpequal but only emits WLogWARN, execution continues. The wrapped value 247 is used as a shift exponent, causing undefined behavior...

CVE-2026-33977

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, a malicious RDP server can crash the FreeRDP client by sending audio data in IMA ADPCM format with an invalid initial step index value = 89. The unvalidated step index is read directly from the network and...

CVE-2026-33985

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, pixel data from adjacent heap memory is rendered to screen, potentially leaking sensitive data to the attacker. This issue has been patched in version 3.24.2...

CVE-2026-33982

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, there is a heap-buffer-overflow READ vulnerability at 24 bytes before the allocation, in winpralignedoffsetrecalloc. This issue has been patched in version 3.24.2...

CVE-2026-33952

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, an unvalidated authlength field read from the network triggers a WINPRASSERT failure in rtsreadauthverifiernochecks, causing any FreeRDP client connecting through a malicious RDP Gateway to crash with SIGABR...
