In Tenda AC15 V15.03.05.19, the function GetValue contains a stack-based buffer overflow vulnerability.

RIOT-OS, an operating system that supports Internet of Things devices, contains a network stack with the ability to process 6LoWPAN frames. Prior to version 2022.10, an attacker can send a crafted frame to the device resulting in a NULL pointer dereference. During forwarding of a fragment an uninitialized entry in the reassembly buffer is used. The NULL pointer dereference triggers a hard fault exception resulting in denial of service. Version 2022.10 fixes this issue. As a workaround, disable support for fragmented IP datagrams or apply the patches manually.

RIOT-OS, an operating system that supports Internet of Things devices, contains a network stack with the ability to process 6LoWPAN frames. Prior to version 2022.10, an attacker can send a crafted frame to the device resulting in an out of bounds write in the packet buffer. The overflow can be used to corrupt other packets and the allocator metadata. Corrupting a pointer will easily lead to denial of service. While carefully manipulating the allocator metadata gives an attacker the possibility to write data to arbitrary locations and thus execute arbitrary code. Version 2022.10 fixes this issue. As a workaround, disable support for fragmented IP datagrams or apply the patches manually.

RIOT-OS, an operating system that supports Internet of Things devices, contains a network stack with the ability to process 6LoWPAN frames. An attacker can send a crafted frame to the device resulting in a large out of bounds write beyond the packet buffer. The write will create a hard fault exception after reaching the last page of RAM. The hard fault is not handled and the system will be stuck until reset. Thus the impact is denial of service. Version 2022.10 fixes this issue. As a workaround, apply the patch manually.

Debian Linux Security Advisory 5393-1 - Multiple security issues were discovered in Chromium, which could result in the execution of arbitrary code, denial of service or information disclosure.

Debian Linux Security Advisory 5392-1 - Multiple security issues were discovered in Thunderbird, which could result in denial of service or the execution of arbitrary code.

In LTOS versions prior to V7.06.013, the configuration file upload function would not correctly validate the input, which would allow an remote authenticated attacker with high privileges to execute arbitrary commands.

Tenda AC15 V15.03.05.19 is vulnerable to Buffer Overflow.

Tenda AC5 V15.03.06.28 is vulnerable to Buffer Overflow via the initWebs function.

Cesanta MJS v2.20.0 was discovered to contain a SEGV vulnerability via mjs_ffi_cb_free at src/mjs_ffi.c. This vulnerability can lead to a Denial of Service (DoS).
