Vulnerabilities 5

  • Low 3.7

    ImageMagick before 7.1.2-31 Division by Zero in FLIF encoder

    ImageMagick before 7.1.2-31 and 6.9.13-56 contains a division-by-zero flaw in the FLIF encoder. An incorrect value for ticks per second in the image being encoded causes a divide-by-zero and crashes the encoder, resulting in a denial of service. The issue is …

  • Low 3.7

    ImageMagick before 7.1.2-31 Policy Bypass in UHDR encoder

    ImageMagick before 7.1.2-31 contains a policy bypass vulnerability in the UHDR encoder that fails to perform policy checks during buffer allocation for image pixels. Attackers can bypass resource policies by processing specially crafted UHDR images, potential…

  • Low 3.3

    ImageMagick before 7.1.2-31 Policy Bypass via PCD decoder

    ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a policy bypass in the PCD (and, per the upstream advisory, CUBE and HALD) coder: when a specific command line option is supplied, the decoder does not check a configured resource limit, which can resu…

  • Low 3.1

    ImageMagick before 7.1.2-31 Null Pointer Dereference via PNM

    ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a NULL pointer dereference in the PNM coder. When the coder reaches a memory (resource) limit at a specific point during processing, the failed allocation is not handled and a NULL pointer is dereferen…

  • Low 2.9

    ImageMagick before 7.1.2-31 Use After Free via ImagesToBlob

    ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a use-after-free vulnerability in the ImagesToBlob method, caused by a pointer that is not updated correctly. Exploitation may result in a limited availability impact (e.g., a crash of the affected pro…
