CVE-2006-5824

Estado: ModificadaMedia (4.9)—

Integer overflow in the ffs_rdextattr function in FreeBSD 6.1 allows local users to cause a denial of service (kernel panic) and trigger a heap-based buffer overflow via a crafted UFS filesystem, a different vulnerability than CVE-2006-5679. NOTE: a third party states that this issue does not cross privilege boundaries in FreeBSD because only root may mount a filesystem.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
