CVE-2020-19131

Buffer Overflow in LibTiff v4.0.10 allows attackers to cause a denial of service via the "invertImage()" function in the component "tiffcrop".

The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.

Security Fix(es):

• libtiff: a buffer overflow via the "invertImage()" may lead to DoS (CVE-2020-19131)

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)

It was discovered that LibTIFF was not properly performing the calculation of data that would eventually be used as a reference for bound-checking operations. An attacker could possibly use this issue to cause a denial of service or to expose sensitive information. This issue only affected Ubuntu 18.04 LTS. (CVE-2020-19131)

It was discovered that LibTIFF was not properly terminating a function execution when processing incorrect data. An attacker could possibly use this issue to cause a denial of service or to expose sensitive information. This issue only affected Ubuntu 18.04 LTS. (CVE-2020-19144)

It was discovered that LibTIFF did not properly manage memory under certain circumstances. If a user were tricked into opening a specially crafted TIFF file using tiffinfo tool, an attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2022-1354)

It was discovered that LibTIFF did not properly manage memory under certain circumstances. If a user were tricked into opening a specially crafted TIFF file using tiffcp tool, an attacker could possibly use this issue to
cause a denial of service. (CVE-2022-1355)

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 behaviour situation via a specially crafted file. An attacker could possibly use this issue to cause a denial of service. (CVE-2022-2056, CVE-2022-2057, CVE-2022-2058)
