CVE-2026-59267 2026-11-04 N/A
A crafted DXF document causes a heap buffer overflow in Draw in Apache OpenOffice 4.1.16 and earlier. This could cause a crash or otherwise a corruption of memory areas. Users are recommended to upgrade to version 4.1.17, which fixes this issue.
CVE-2026-121941 2026-11-04 7.8 High
libmt32emu before 2.8.4 contains a heap buffer overflow vulnerability in MidiStreamParserImpl::parseSysex that allows attackers to write past a heap allocation by supplying oversized unterminated SysEx messages. Attackers can feed more than 32768 SysEx data bytes through the mt32emu_parse_stream API via MIDI files, ports, or sequencer clients to corrupt heap memory and crash the application.
CVE-2026-121156 1 Google 1 Chrome 2026-11-04 9.6 Critical

CVE-2026-119727 2 Red Hat, Redhat 2 Enterprise Linux, Enterprise Linux 2026-11-04 6.5 Medium
A flaw was found in GStreamer's gst-plugins-bad H.265 video parser. When parsing a specially crafted H.265 bitstream containing a Screen Content Coding (SCC) extension with certain palette predictor initializer settings, an integer underflow in the upper-bound computation allows the parser to accept an out-of-range value for the number of palette predictor entries. This causes the parser to write beyond the end of a fixed-size array, resulting in memory corruption and an application crash. An attacker can deliver the malformed bitstream as a local file or over a network stream such as HTTP, HLS, DASH, RTSP, RTP, or WebRTC. Successful exploitation requires the application to open or play that content, and is limited to a denial-of-service impact.

An attacker in radio range may be able to cause unexpected system termination.
CVE-2026-114549 1 Nomachine 1 Nomachine 2026-11-04 N/A
NoMachine nxwebrunner Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of NoMachine. Authentication is not required to exploit this vulnerability. The specific flaw exists within the web service, which listens on TCP port 4443 by default. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-30685.
CVE-2026-121047 1 Google 1 Chrome 2026-11-04 8.8 High
Buffer overflow in Media in Google Chrome prior to 157.0.8103.38 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: High)

CVE-2026-58547 1 Microsoft 16 Windows 10 1809, Windows 10 21h2, Windows 10 21h2 and 13 more 2026-11-03 5.5 Medium

CVE-2026-57156 1 Freerdp 1 Freerdp 2026-11-03 9.8 Critical
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0 on 32-bit builds, FreeRDP clients contain an integer overflow in update_read_delta_points in libfreerdp/core/orders.c when multiplying an attacker-controlled point count by sizeof(DELTA_POINT), allowing a malicious RDP peer to allocate an undersized heap buffer and then write beyond it during initialization. This issue is fixed in version 3.28.0.
CVE-2026-50447 1 Microsoft 18 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 15 more 2026-11-03 9.8 Critical
Heap-based buffer overflow in Windows Message Queuing allows an unauthorized attacker to execute code over a network.
CVE-2026-44420 1 Freerdp 1 Freerdp 2026-11-03 8.8 High
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.26.0, a malicious RDP client can trigger a heap-buffer-overflow write in FreeRDP's server-side clipboard (cliprdr) channel by sending a CB_CLIP_CAPS PDU with a too-small capabilitySetLength. This can crash the server process (remote DoS) and may be exploitable for code execution because it corrupts heap memory. This vulnerability is fixed in 3.26.0.
CVE-2026-42533 1 F5 5 Nginx Gateway Fabric, Nginx Ingress Controller, Nginx Open Source and 2 more 2026-11-03 8.1 High
A vulnerability exists in NGINX Plus and NGINX Open Source when a map directive uses regex matching and a string expression references the map's regex capture variables before referencing the map output variable. Alternatively, the same result could be achieved by using a non-cacheable variable in a string expression under certain conditions. An unauthenticated attacker along with conditions beyond their control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Impact: This vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system or to possibly trigger a code execution. There is no control plane exposure; this is a data plane issue only.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
CVE-2026-121113 1 Google 1 Chrome 2026-11-03 N/A
Buffer overflow in PDFium in Google Chrome prior to 157.0.8103.38 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted PDF file. (Chromium security severity: High)
