5Description
A vulnerability was determined in mxml up to 4.0.4. This issue affects the function index_sort of the file mxml-index.c of the component mxmlIndexNew. Executing a manipulation of the argument tempr can lead to stack-based buffer overflow. The attack is restricted to local execution. The exploit has been publicly disclosed and may be utilized. This patch is called 6e27354466092a1ac65601e01ce6708710bb9fa5. A patch should be applied to remediate this issue.
Analysis
Stack-based buffer overflow in mxml up to version 4.0.4 allows local authenticated attackers to cause a denial of service by manipulating the tempr argument in the index_sort function within mxmlIndexNew. The vulnerability has a low CVSS score of 3.3 due to local-only attack vector and denial-of-service impact, but publicly available exploit code exists and a vendor patch has been released.
