It was discovered that HTMLDOC incorrectly handled memory in the image_set_mask, git_read_lzw, write_header and write_node functions, which could lead to a heap buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2022-0137, CVE-2022-24191, CVE-2022-34033, CVE-2022-34035) It was discovered that HTMLDOC incorrectly handled memory in the gif_get_code function, which could lead to a segmentation fault. If a user or application were tricked into opening a crafted GIF file, an attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2022-0534) It was discovered that HTMLDOC did not perform proper bounds checks on image dimensions when loading JPEG images, which could lead to a buffer overflow.
