CVE-2012-2152

Status: ModifiedHigh (7.5)—

Stack-based buffer overflow in the get_packet method in socket.c in dhcpcd 3.2.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long packet.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
