CVE-2021-1373 1 Cisco 8 Catalyst 9300, Catalyst 9400, Catalyst 9500 and 5 more 2026-06-17 7.8 HIGH 8.6 HIGH
A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Wireless Controller Software for the Cisco Catalyst 9000 Family Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition of an affected device. The vulnerability is due to insufficient validation of CAPWAP packets. An attacker could exploit this vulnerability by sending a malformed CAPWAP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to crash and reload, resulting in a DoS condition.
CVE-2020-8244 2 Bufferlist Project, Debian 2 Bufferlist, Debian Linux 2026-06-17 6.4 MEDIUM 6.5 MEDIUM
A buffer over-read vulnerability exists in bl <4.0.3, <3.0.1, <2.2.1, and <1.2.3 which could allow an attacker to supply user input (even typed) that if it ends up in consume() argument and can become negative, the BufferList state can be corrupted, tricking it into exposing uninitialized memory via regular .slice() calls.
CVE-2020-3399 1 Cisco 7 Catalyst 9800-40, Catalyst 9800-80, Catalyst 9800-cl and 4 more 2026-06-17 7.8 HIGH 8.6 HIGH
A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition of an affected device. The vulnerability is due to insufficient input validation during CAPWAP packet processing. An attacker could exploit this vulnerability by sending a crafted CAPWAP packet to an affected device, resulting in a buffer over-read. A successful exploit could allow the attacker to cause the affected device to crash and reload, resulting in a DoS condition on the affected device.
CVE-2020-35511 2 Debian, Libpng 2 Debian Linux, Pngcheck 2026-06-17 N/A 7.8 HIGH
A global buffer overflow was discovered in pngcheck function in pngcheck-2.4.0(5 patches applied) via a crafted png file.
CVE-2020-25853 1 Realtek 2 Rtl8195a, Rtl8195a Firmware 2026-06-17 5.0 MEDIUM 7.5 HIGH
The function CheckMic() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for an internal function, _rt_md5_hmac_veneer() or _rt_hmac_sha1_veneer(), resulting in a stack buffer over-read which can be exploited for denial of service. An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker does not need to know the network's PSK.
CVE-2019-5432 1 Mqtt-packet Project 1 Mqtt-packet 2026-06-17 5.0 MEDIUM 7.5 HIGH
A specifically malformed MQTT Subscribe packet crashes MQTT Brokers using the mqtt-packet module versions < 3.5.1, 4.0.0 - 4.1.3, 5.0.0 - 5.6.1, 6.0.0 - 6.1.2 for decoding.
CVE-2019-3563 1 Facebook 1 Wangle 2026-06-17 7.5 HIGH 9.8 CRITICAL
Wangle's LineBasedFrameDecoder contains logic for identifying newlines which incorrectly advances a buffer, leading to a potential underflow. This affects versions of Wangle prior to v2019.04.22.00
CVE-2019-11036 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-06-17 6.4 MEDIUM 9.1 CRITICAL
When processing certain files, PHP EXIF extension in versions 7.1.x below 7.1.29, 7.2.x below 7.2.18 and 7.3.x below 7.3.5 can be caused to read past allocated buffer in exif_process_IFD_TAG function. This may lead to information disclosure or crash.
CVE-2019-1010220 1 Tcpdump 1 Tcpdump 2026-06-17 4.3 MEDIUM 3.3 LOW
tcpdump.org tcpdump 4.9.2 is affected by: CWE-126: Buffer Over-read. The impact is: May expose Saved Frame Pointer, Return Address etc. on stack. The component is: line 234: "ND_PRINT((ndo, "%s", buf));", in function named "print_prefix", in "print-hncp.c". The attack vector is: The victim must open a specially crafted pcap file.
