Summary: graphicsmagick vulnerabilities

Details: It was discovered that GraphicsMagick was not properly performing bounds checks when processing TGA image files, which could lead to a heap buffer overflow. If a user or automated system were tricked into processing a specially crafted TGA image file, an attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. (CVE-2018-20184) It was discovered that GraphicsMagick was not properly validating bits per pixel data when processing DIB image files. If a user or automated system were tricked into processing a specially crafted DIB image file, an attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. (CVE-2018-20189) It was discovered that GraphicsMagick was not properly processing bit-field mask values in BMP image files, which could result in the execution of an infinite loop. If a user or automated system were tricked into processing a specially crafted BMP image file, an attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. (CVE-2018-5685) It was discovered that GraphicsMagick was not properly validating data used in arithmetic operations when processing MNG image files, which could result in a divide-by-zero error. If a user or automated system were tricked into processing a specially crafted MNG image file, an attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. (CVE-2018-9018) It was discovered that GraphicsMagick was not properly performing bounds checks when processing MIFF image files, which could lead to a heap buffer overflow. If a user or automated system were tricked into processing a specially crafted MIFF image file, an attacker could possibly use this issue to cause a denial of service or expose sensitive information. This issue only affected Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. (CVE-2019-11006) It was discovered that GraphicsMagick did not properly magnify certain MNG image files, which could lead to a heap buffer overflow. If a user or automated system were tricked into processing a specially crafted MNG image file, an attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 20.04 LTS. (CVE-2020-12672) It was discovered that GraphicsMagick was not properly performing bounds checks when parsing certain MIFF image files, which could lead to a heap buffer overflow. If a user or automated system were tricked into processing a specially crafted MIFF image file, an attacker could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2022-1270)
