1) Out-of-bounds read (CVE-ID: CVE-2019-10714)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when processing images within the LocaleLowercase() function in MagickCore/locale.c. A remote attacker can create a specially crafted image, pass it to the affected application, trigger out-of-bounds read error and perform denial of service (DoS) attack.
