An attacker could possibly use this issue to cause a denial of service or to expose sensitive information. (CVE-2022-0924) It was discovered that LibTIFF was not properly performing the calculation of data that would eventually be used as a reference for bounds checking operations, which could lead to an out-of-bounds read via a specially crafted file. An attacker could possibly use this issue to cause a denial of service or to expose sensitive information. (CVE-2020-19131) It was discovered that LibTIFF was not properly terminating a function execution when processing incorrect data, which could lead to an out-of-bounds read via a specially crafted file. An attacker could possibly use this issue to cause a denial of service or to expose sensitive information. (CVE-2020-19144) It was discovered that LibTIFF was not properly performing checks when setting the value for data later used as reference during memory access, which could lead to an out-of-bounds read via a specially crafted file. An attacker could possibly use this issue to cause a denial of service or to expose sensitive information. (CVE-2022-22844)
