CVE-2021-32975

Status: ModifiedHigh (7.8)—

Cscape (All Versions prior to 9.90 SP5) lacks proper validation of user-supplied data when parsing project files. This could lead to an out-of-bounds read. An attacker could leverage this vulnerability to execute code in the context of the current process.

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).
