Title:	Ubuntu: Security Advisory (USN-5523-2)
Summary:	The remote host is missing an update for the 'tiff' package(s) announced via the USN-5523-2 advisory.
Description:	Summary: The remote host is missing an update for the 'tiff' package(s) announced via the USN-5523-2 advisory. Vulnerability Insight: USN-5523-1 fixed several vulnerabilities in LibTIFF. This update provides the fixes for CVE-2022-0907, CVE-2022-0908, CVE-2022-0909, CVE-2022-0924 and CVE-2022-22844 for Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. Original advisory details: It was discovered that LibTIFF was not properly perf orming 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) Affected Software/OS: 'tiff' package(s) on Ubuntu 18.04, Ubuntu 20.04. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:N/A:P
