7.8
CVSS v3.1
Official Description
Integer overflow in the jpc_dec_process_siz function in libjasper/jpc/jpc_dec.c in JasPer before 1.900.13 allows remote attackers to have unspecified impact via a crafted file, which triggers an assertion failure.
Technical Analysis
CVE-2016-9387 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
