httpd: Apache HTTP Server: Heap-based Buffer Overflow via untrusted content in mod_xml2enc
A flaw was found in Apache HTTP Server, specifically within the modxml2enc module. This heap-based buffer overflow vulnerability can be triggered when processing untrusted content through the xml2StartParse function. A remote attacker could potentially exploit this to cause a denial of service,...
httpd: Apache HTTP Server: Heap-based Buffer Overflow via malicious backend servers
A flaw was found in Apache HTTP Server. This heap-based buffer overflow vulnerability can be exploited by a malicious backend server when using ProxyPassReverseCookie directives. This could lead to a denial of service DoS condition, making the server unavailable to legitimate users...

CVE-2026-55193: Heap-based Buffer Overflow
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, FreeRDP clients using TS Gateway accept a server-controlled maxxmitfrag value in libfreerdp/core/gateway/rpcbind.c without bounding it to the 4088-byte ReceiveFragment allocation. A malicious gateway can advertise...
CVE-2026-55194: Heap-based Buffer Overflow
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, rpcclientrecvfragment in libfreerdp/core/gateway/rpcclient.c ensures the response reassembly stream capacity using only the server-declared allochint rather than the actual StubLength about to be written. A maliciou...
CVE-2026-63633: Heap-based Buffer Overflow
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, freerdpdspdecodeopus in libfreerdp/codec/dsp.c calls StreamEnsureRemainingCapacity on context-common.buffer even though opusdecode writes decoded PCM into the caller-supplied out stream. A malicious RDP server that...

CVE-2026-55191: Heap-based Buffer Overflow
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, FreeRDP clients that negotiate RDPGFX AVC444 with an H.264 decoder backend calculate the intermediate YUV444 allocation size in libfreerdp/codec/h264.c with 32-bit multiplication in avc444ensurebuffer. A malicious R...
