CVE-2011-0520
Last modified
CVE-2011-0520 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 5.17% chance of exploitation in the next 30 days.
