CVE-2026-48691 1 Pavel-odintsov 1 Fastnetmon 2026-05-28 7.3 High
FastNetMon Community Edition through 1.2.9 contains an integer overflow in the BGP AS_PATH attribute encoder. In src/bgp_protocol.hpp, the IPv4UnicastAnnounce::get_attributes() function computes attribute_length as 'sizeof(bgp_as_path_segment_element_t) + this->as_path_asns.size() * sizeof(uint32_t)' and stores it in a uint8_t field (line 600-605). Since uint8_t can only hold values 0-255, an AS_PATH containing more than 63 ASNs (2 + 64*4 = 258 > 255) causes silent truncation. The truncated length is used for buffer sizing, while the actual data written is the full untruncated amount, resulting in a heap buffer overflow. Similarly, the path_segment_length field at line 621 is also uint8_t, truncating with more than 255 ASNs.
CVE-2025-70103 2026-05-27 7.3 High
Heap buffer overflow vulnerability in libjxl 0.12.0 via crafted PBM images to the jxl::extras::DecodeImagePNM function in file lib/extras/dec/pnm.cc.
CVE-2026-9541 2 Squirrel, Squirrel-lang 2 Squirrel, Squirrel 2026-05-27 5.3 Medium
A security flaw has been discovered in Squirrel up to 3.2. Impacted is the function ReadObject of the file squirrel/sqobject.cpp of the component Cnut File Handler. Performing a manipulation results in heap-based buffer overflow. The attack is only possible with local access. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2026-4391 1 Teamspeak 3 Server 1 Teamspeak 3 Server 2026-05-27 5.3 Medium
A security vulnerability has been detected in TeamSpeak 3 Server up to 3.13.7. This vulnerability affects unknown code of the component ECC Key Parser. Such manipulation leads to heap-based buffer overflow. The attack may be launched remotely. Upgrading to version 3.13.8 is able to resolve this issue. It is suggested to upgrade the affected component.
CVE-2026-48135 1 Checkpoint 1 Quantum Security Gateway 2026-05-27 5.3 Medium
A Check Point HTTP-based service can incorrectly handle malformed HTTP requests. The issue is related to HTTP request parsing and validation.
CVE-2022-28234 3 Adobe, Apple, Microsoft 6 Acrobat, Acrobat Dc, Acrobat Reader and 3 more 2026-05-27 7.8 High
Acrobat Reader DC versions 22.001.20085 (and earlier), 20.005.3031x (and earlier) and 17.012.30205 (and earlier) is affected by a heap-based buffer overflow vulnerability due to insecure handling of a crafted .pdf file, potentially resulting in arbitrary code execution in the context of the current user. Exploitation requires user interaction in that a victim must open a crafted .pdf file
CVE-2026-48690 1 Pavel-odintsov 1 Fastnetmon 2026-05-27 7.1 High
FastNetMon Community Edition through 1.2.9 contains an integer overflow vulnerability in the packet capture buffer allocation. In src/packet_storage.hpp, the allocate_buffer() function computes memory_size_in_bytes as 'buffer_size_in_packets * (max_captured_packet_size + sizeof(fastnetmon_pcap_pkthdr_t)) + sizeof(fastnetmon_pcap_file_header_t)' using unsigned int (32-bit) arithmetic. With max_captured_packet_size=1500 and sizeof(fastnetmon_pcap_pkthdr_t)=16, each packet requires approximately 1516 bytes. If buffer_size_in_packets exceeds approximately 2,832,542, the multiplication overflows, resulting in a much smaller allocation than expected. Subsequent write_packet() calls then write past the allocated buffer, causing heap corruption. The buffer_size_in_packets value is derived from the ban_details_records_count configuration parameter, which is parsed using atoi() with no overflow checking.
CVE-2026-44983 1 Servo 1 Smallvec 2026-05-27 7.3 High
smallbitvec is a growable bit-vector for Rust, optimized for size. From 1.0.1 to 2.6.0, an integer overflow in the internal capacity calculation of smallbitvec can lead to an undersized heap allocation, resulting in a heap buffer overflow through safe APIs only. This allows memory corruption without requiring unsafe code from the caller. This vulnerability is fixed in 2.6.1.
CVE-2026-7310 1 Hitachienergy 1 Mach Hidraw 2026-05-27 N/A
A heap-based buffer overflow vulnerability exists in XML parser functionality in the HiDraw. An authenticated malicious user with local access can exploit this vulnerability using a specially crafted XML file which may lead to memory corruption and potential arbitrary code execution. Successful exploitation could result in application crashes (denial of service) and compromise the confidentiality and integrity of the affected system.
CVE-2025-14087 2 Gnome, Redhat 11 Glib, Enterprise Linux, Enterprise Linux Eus and 8 more 2026-05-27 5.6 Medium
A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap corruption, leading to a denial of service or potential code execution via a buffer-underflow in the GVariant parser when processing maliciously crafted input strings.
CVE-2026-2651 1 Mlflow 1 Mlflow/mlflow 2026-05-27 9.0 Critical
A vulnerability in MLflow versions <=3.10.1.dev0 allows unauthorized access to multipart upload (MPU) endpoints when the `--serve-artifacts` mode is enabled. The authorization logic does not enforce resource-level permission checks for `/mlflow-artifacts/mpu/*` endpoints, enabling attackers to overwrite artifacts belonging to other users. This can lead to unauthorized cross-user writes, model supply chain poisoning, and arbitrary code execution when compromised models are loaded. The issue is resolved in version 3.10.0.
CVE-2026-48689 1 Pavel-odintsov 1 Fastnetmon 2026-05-27 9.8 Critical
FastNetMon Community Edition through 1.2.9 contains an off-by-one heap-based buffer overflow in the dynamic_binary_buffer_t class (src/dynamic_binary_buffer.hpp). Five methods (append_dynamic_buffer, append_data_as_pointer, append_data_as_object_ptr, memcpy_from_ptr, memcpy_from_object_ptr) use an incorrect bounds check of the form 'if (offset + length > maximum_internal_storage_size + 1)' instead of the correct 'if (offset + length > maximum_internal_storage_size)'. This allows writing exactly one byte past the end of the heap-allocated buffer. The class is used pervasively in BGP message encoding/decoding, NetFlow template processing, and Flow Spec NLRI construction. An attacker who can send network traffic (NetFlow, sFlow, IPFIX, or BGP) to a FastNetMon instance can trigger this overflow, potentially achieving arbitrary code execution by corrupting heap metadata. Notably, the append_byte() method uses the correct bounds check, confirming the inconsistency.
CVE-2026-8834 3 Ibm, Linux, Microsoft 5 Aix, Http Server, Z\/os and 2 more 2026-05-26 8 High
IBM HTTP Server 8.5, and 9.0 contains a buffer overflow vulnerability. A privileged user, authenticated to the Administration Server, could exploit this vulnerability to execute remote code or cause a denial of service.

CVE-2026-40033 1 Freerdp 1 Freerdp 2026-05-26 8.8 High
FreeRDP before 3.26.0 contains a heap-buffer-overflow vulnerability in gdi_CacheToSurface that allows remote attackers to write out-of-bounds heap memory. The vulnerability occurs because rectangle validation clamps coordinates to UINT16_MAX but performs copy operations using unclamped cache entry dimensions, enabling malicious RDP servers to trigger large out-of-bounds writes and potentially achieve remote code execution or client crash.
CVE-2026-48131 1 Checkpoint 1 Quantum Security Gateway 2026-05-26 8.1 High
The VPN service may mishandle an unexpected IKE fragment value received on the IKE port 500/UDP during the early stage of a connection attempt. This can cause the service to terminate unexpectedly, resulting in denial of service (temporary disruption of VPN-related functionality).
CVE-2026-43390 1 Linux 1 Linux Kernel 2026-05-26 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: nstree: tighten permission checks for listing Even privileged services should not necessarily be able to see other privileged service's namespaces so they can't leak information to each other. Use may_see_all_namespaces() helper that centralizes this policy until the nstree adapts.
CVE-2026-43391 1 Linux 1 Linux Kernel 2026-05-26 8.8 High
In the Linux kernel, the following vulnerability has been resolved: nsfs: tighten permission checks for handle opening Even privileged services should not necessarily be able to see other privileged service's namespaces so they can't leak information to each other. Use may_see_all_namespaces() helper that centralizes this policy until the nstree adapts.
