CVE-2023-51890:
Linux Debian vulnerability analysis and mitigation
Overview
An infinite loop issue discovered in Mathtex 1.05 and before allows remote attackers to consume CPU resources via crafted string in the application URL (NVD, Yulun Blog).
Technical details
The vulnerability exists in the application's handling of certain calendar-related inputs. When processing inputs like '\calendara', the application enters an infinite loop, causing excessive CPU consumption. Similar inputs like '\calendarx' and '\calendarz' can also trigger this vulnerability, while '\calendar0' does not cause the issue (Yulun Blog).
Impact
When successfully exploited, this vulnerability allows attackers to cause denial of service by consuming CPU resources on the target server through a crafted URL request (NVD). The CVSS v3.1 base score is 7.5 HIGH, with vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H (NVD).
Mitigation and workarounds
Users should upgrade to a version newer than Mathtex 1.05 when available. No specific workarounds have been publicly documented (NVD).
