tiff vulnerabilities

It was discovered that LibTIFF was not properly performing checks to guarantee that allocated memory space existed, which could lead to a NULL pointer dereference via a specially crafted file. An attacker could possibly use this issue to cause a denial of service. (CVE-2022-0907, CVE-2022-0908)

It was discovered that LibTIFF was not properly performing checks to avoid division calculations where the denominator value was zero, which could lead to an undefined behavior situation via a specially crafted file. An attacker could possibly use this issue to cause a denial of service. (CVE-2022-0909)

It was discovered that LibTIFF was not properly performing bounds checks, 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-2022-0924)

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)
