GHSA-7VQ7-QCWQ-J3VC

Vulnerability from github – Published: 2022-05-17 02:02 – Updated: 2022-05-17 02:02

Details

The compress_add_dlabel_points function in dns/Compress.c in MaraDNS 1.4.03, 1.4.05, and probably other versions allows remote attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a long DNS hostname with a large number of labels, which triggers a heap-based buffer overflow.
