CVE-2023-51889: 
Linux Debian vulnerability analysis and mitigation

Stack Overflow vulnerability in the validate() function in Mathtex v.1.05 and before allows a remote attacker to execute arbitrary code via crafted string in the application URL. The vulnerability was discovered and disclosed in January 2024, affecting all versions of Mathtex up to and including version 1.05 (NVD, Ubuntu).

The vulnerability exists in the validate() function where the buffer 'display' has a length of only 2048 bytes. When processing input that exceeds this buffer size, an out-of-bounds writing occurs resulting in a stack overflow condition. This vulnerability has been assigned a CVSS v3.1 base score of 9.8 (CRITICAL) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating it can be exploited remotely without requiring privileges or user interaction (NVD, Yulun Blog).

The successful exploitation of this vulnerability can lead to remote code execution on the affected system. Due to the stack overflow condition, an attacker can potentially execute arbitrary code with the privileges of the application, potentially compromising the security of the entire system (NVD).

As of the current data, there is no official patch available for this vulnerability. Users of affected versions should consider upgrading to a newer version when available or implementing access controls to limit exposure to untrusted input (NVD).
