EUVD-2026-50399

Xlight FTP Server before 3.9.5 contains a pre-authentication stack buffer overflow vulnerability that allows unauthenticated attackers to corrupt stack memory by sending malformed SSH packets when a GCM cipher is negotiated. Attackers can craft packets with an unvalidated length field passed...

Rockwell Automation Micro850/870 Dependency on Vulnerable Third-Party Component (CVE-2025-13823)

A security issue was found in the IPv6 stack in the Micro850 and Micro870 controllers. This issue occurs when the controllers receive multiple malformed packets, causing the controller to enter a recoverable fault fault code 0xFE60. To recover the controller, the fault must be cleared. This plugi...

PT-2026-65628

A flaw was found in Samba's internal DNS server where unauthenticated TKEY registration requests were added to the TKEY name cache before being rejected. A remote, unauthenticated attacker can exploit this behavior by sending a large number of TKEY requests with arbitrary names, exhausting the...

EUVD-2026-43603

EIPStackGroup OpENer 2.3.0 commit 76b95cf has an out-of-bounds read issue in Connection Manager handling of ForwardOpen requests when processing short malformed packets. An attacker can send a valid ENIP outer frame carrying a malformed CIP ForwardOpen/LargeForwardOpen request, causing the parser...

PYSEC-2026-3437 zeroconf: Unbounded exception-dedup state retains packet buffers via traceback frame locals, enabling LAN-local memory exhaustion

Impact DNSIncoming.logexceptiondebug and the four QuietLogger exception-dedup methods stored an unbounded seenlogs dict keyed by strsys.excinfo1. The seven IncomingDecodeError messages raised from readname / decodelabelsatoffset RFC 6762 §18 name-decoding error paths all embed self.source — the...

CVE-2026-51537

OpENer 2.3.0 (commit 76b95cf) contains an out-of-bounds read in the Connection Manager when processing malformed ForwardOpen/LargeForwardOpen requests, allowing a remote attacker to trigger the issue over the network without authentication. Red Hat notes potential denial of service or information...

An Improper Validation of Specified Quantity in Input vulnerability in the Packet Forwarding Engine pfe of Juniper Networks Junos OS on MX Series allows an unauthenticated, adjacent attacker to cause a Denial-of-Service DoS. When a specific packet is received from device in the same broadcast...

wireshark: Heap-based Buffer Overflow in Wireshark

A flaw was found in the RDP protocol dissector in Wireshark. This issue occurs when malformed packets are decoded from a pcap file or the network, causing a heap-based buffer overflow, resulting in a denial of service or potentially in code execution...

wireshark: Buffer Over-read in Wireshark

A flaw was found in the RF4CE Profile dissector in Wireshark. This issue occurs when malformed packets are decoded from a pcap file or the network, causing a buffer over-read, resulting in a denial of service...

wireshark: Improperly Controlled Sequential Memory Allocation in Wireshark

A flaw was found in the USB HID dissector in Wireshark. This issue occurs when malformed packets are decoded from a pcap file or the network, causing an excessive consumption of memory, resulting in a denial of service...

DEBIAN-CVE-2026-52721

Multiple out-of-bounds read vulnerabilities were found in GStreamer's pcapparse element. Malformed PCAP records can trigger reads beyond buffer boundaries during IPv4/TCP header parsing. This element is primarily used in debugging pipelines, limiting real-world exposure. A local attacker could...
