CVE-2017-12467

Status: ModifiedHigh (7.5)—

Memory leak in CCN-lite before 2.00 allows context-dependent attackers to cause a denial of service (memory consumption) by leveraging failure to allocate memory for the comp or complen structure member.

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).
