Summary
libgd2 vulnerabilities
Details
Stefan Esser discovered that the GD library incorrectly handled memory when processing certain images. If a user or automated system were tricked into processing a specially crafted image, an attacker could cause a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-10166)
It was discovered that the GD library incorrectly handled certain malformed images. If a user or automated system were tricked into processing a specially crafted image, an attacker could cause a denial of service. (CVE-2016-10167)
It was discovered that the GD library incorrectly handled certain malformed images. If a user or automated system were tricked into processing a specially crafted image, an attacker could cause a denial of service, or possibly execute arbitrary code. (CVE-2016-10168)
Ibrahim El-Sayed discovered that the GD library incorrectly handled certain malformed TGA images. If a user or automated system were tricked into processing a specially crafted TGA image, an attacker could cause a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-6906)
Ibrahim El-Sayed discovered that the GD library incorrectly handled certain malformed WebP images. If a user or automated system were tricked into processing a specially crafted WebP image, an attacker could cause a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-6912)
It was discovered that the GD library incorrectly handled creating oversized images. If a user or automated system were tricked into creating a specially crafted image, an attacker could cause a denial of service. (CVE-2016-9317)
It was discovered that the GD library incorrectly handled filling certain images. If a user or automated system were tricked into filling an image, an attacker could cause a denial of service. (CVE-2016-9933)
