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 perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources in PsdImagePlugin.PsdImageFile method. A remote attacker can pass specially crafted file to the application and perform a denial of service (DoS) attack.
2) Resource management error (CVE-ID: CVE-2021-28678)
CWE-ID: CWE-399 - Resource Management Errors
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 perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources in BlpImagePlugin. A remote attacker can pass specially crafted file to the application and perform a denial of service (DoS) attack.
3) Out-of-bounds read (CVE-ID: CVE-2021-25287)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/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 in Jpeg2KDecode method. A remote attacker can create a specially crafted J2k image, trigger out-of-bounds read error and read contents of memory on the system.
4) Out-of-bounds read (CVE-ID: CVE-2021-25288)
CWE-ID: CWE-125 - Out-of-bounds read
