This security bulletin contains information about 7 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2020-18771)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack or gain access to sensitive information.
The vulnerability exists due to global buffer over-read in Exiv2::Internal::Nikon1MakerNote::print0x0088 in nikonmn_int.cpp. A remote attacker can perform a denial of service attack or gain access to sensitive information.
2) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2020-18899)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an uncontrolled memory allocation in DataBufdata(subBox.length-sizeof(box)) function. 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-2025-54080)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in Exiv2::EpsImage::writeMetadata() function. A remote attacker can create a specially crafted EPS file, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.
4) Incorrect calculation (CVE-ID: CVE-2025-55304)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to usage of a quadratic algorithm within the jpegBase::readMetadata() function during ICC profile parsing. A remote attacker can trick the victim into opening a specially crafted image file and crash the application.
5) Out-of-bounds read (CVE-ID: CVE-2026-25884)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to a boundary condition in the CRW image parser. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger an out-of-bounds read error and perform a denial of service attack.
6) Out-of-bounds read (CVE-ID: CVE-2026-27596)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to a boundary condition within the LoaderNative::getData() function in the preview component. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.
7) Integer overflow (CVE-ID: CVE-2026-27631)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to integer overflow in the preview component. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and perform a denial of service attack.
