1) Integer overflow (CVE-ID: CVE-2019-9959)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in the "JPXStream::init" function, caused by a failure to bounds-check user-supplied data before copying it to an undersized memory buffer. A remote attacker can supply crafted data to the system, trigger integer overflow and cause a denial of service condition on the targeted system.
