CVE-2026-67873 1 Mz-automation 1 Lib60870 2026-08-07 9.8 Critical
A heap-based buffer overflow exists in lib60870-C 2.4.0 in the server-side FileSegment ASDU encoding path. The issue occurs because FileSegment_encode() validates only the standalone segment length via FileSegment_GetMaxDataSize() and does not verify the residual capacity of the current ASDU frame before encoding object fields and segment data
CVE-2026-19138 1 Google 1 Chrome 2026-08-07 8.3 High
Heap buffer overflow in CrashReporting in Google Chrome prior to 151.0.7922.109 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
CVE-2026-56208 2 Aomedia, Redhat 7 Libaom, Ai Inference Server, Enterprise Linux and 4 more 2026-08-06 7.6 High
A heap buffer overflow vulnerability was found in libaom, the reference AV1 codec implementation. A flaw in the AV1 encoder's Look-Ahead Processing (LAP) mode causes the first-pass stats ring buffer wrap-around guard to be bypassed when g_lag_in_frames is set to 1 or higher. This results in a 232-byte out-of-bounds write on every encoded frame after the second, corrupting adjacent heap objects. An attacker who can influence encoder configuration in a transcoding service or WebRTC session could exploit this to cause a denial of service (process crash) or potentially achieve code execution.
CVE-2026-67867 1 Systerel 1 S2opc 2026-08-06 7.5 High
Buffer Overflow vulnerability in Systerel S2OPC 1.7.3 allows a remote attacker to cause a denial of service via the Alarm/Conditions wrapper when processing PublishResponse EventNotificationList data
CVE-2026-34501 1 Apache 1 Portable Runtime Utility 2026-08-06 7.5 High
Heap-based Buffer Overflow vulnerability in Apache Portable Runtime Utility redis client. This issue affects Apache Portable Runtime Utility: from 1.6.0 through 1.6.3. Users are recommended to upgrade to version 1.6.4, which fixes the issue.
CVE-2026-34502 1 Apache 1 Portable Runtime Utility 2026-08-06 7.5 High
Heap-based Buffer Overflow vulnerability in Apache Portable Runtime Utility memcached client This issue affects Apache Portable Runtime Utility: from 1.3.0 through 1.6.3.
CVE-2026-67860 1 Open62541 1 Open62541 2026-08-05 7.5 High
open62541 1.5.5 contains a heap-based buffer overflow in the default HistoryRead path when the default history database is used with the memory backend.
CVE-2026-14615 1 Redhat 2 Build Keycloak, Build Of Keycloak 2026-08-05 4.3 Medium
A flaw was found in the Fine-Grained Admin Permissions (FGAP) v2 implementation within Keycloak's administrative services. When FGAP v2 is enabled, the system fails to properly filter child groups based on the caller's specific permissions when requested through a parent group. This allows a delegated administrator to view details of child groups they are not authorized to access directly, including group names, paths, and custom attributes.
CVE-2026-18784 1 Open62541 1 Open62541 2026-08-05 5.3 Medium
A vulnerability was found in o6 open62541 up to 1.5.5. This issue affects the function UA_Client_readNodeClassAttribute of the file src/client/ua_client_highlevel.c. Performing a manipulation results in heap-based buffer overflow. Attacking locally is a requirement. The exploit has been made public and could be used. The project closed the issue report, stating that this is not the official way to report a security vulnerability.
CVE-2026-67859 1 Open62541 1 Open62541 2026-08-05 7.5 High
Buffer Overflow vulnerability in open62541 v1.5.5 allows a remote attacker to cause a denial of service via the Discovery/LDS handling.
CVE-2026-67305 1 Freerdp 1 Freerdp 2026-08-05 7.5 High
FreeRDP Windows client before 3.29.0 contains a heap buffer overflow vulnerability in the clipboard virtual channel when processing CLIPRDR_FILE_CONTENTS_RESPONSE PDUs without validating the server-provided size against the destination buffer. A malicious RDP server can send a response with a data payload significantly larger than requested, causing arbitrary heap memory corruption that may enable remote code execution when a user performs a paste operation.
CVE-2026-68580 1 Freerdp 1 Freerdp 2026-08-05 7.5 High
FreeRDP before 3.29.0 contains integer overflow vulnerabilities in the audio input redirection channel (audin) across ALSA, sndio, WinMM, and OpenSL ES backends that fail to validate the FramesPerPacket parameter from RDP servers. Attackers can supply a malicious FramesPerPacket value causing allocation size wraparound, resulting in heap-based buffer overflow on ALSA or denial of service on all platforms.
CVE-2026-12912 2 Libtiff, Redhat 6 Libtiff, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-08-05 7.3 High
A flaw was found in libtiff. A remote attacker could exploit this vulnerability by providing a specially crafted PixarLog-compressed TIFF image. This issue occurs when decoding Pixarlog codec images with the PIXARLOGDATAFMT_8BITABGR output format and a specific stride value, leading to a heap-based buffer overflow. This could potentially result in arbitrary code execution or a denial of service (DoS).
