\n==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 20.04 LTS
\n– Ubuntu 18.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in LibTIFF.<\/p>\n
Software Description:
\n– tiff: Tag Image File Format (TIFF) library<\/p>\n
Details:<\/p>\n
USN-5523-1 fixed several vulnerabilities in LibTIFF. This update
\nprovides the fixes for CVE-2022-0907, CVE-2022-0908, CVE-2022-0909,
\nCVE-2022-0924 and CVE-2022-22844 for Ubuntu 18.04 LTS and
\nUbuntu 20.04 LTS.<\/p>\n
Original advisory details:<\/p>\n
It was discovered that LibTIFF was not properly perf orming checks to
\nguarantee that allocated memory space existed, which could lead to a
\nNULL pointer dereference via a specially crafted file. An attacker
\ncould possibly use this issue to cause a denial of service.
\n(CVE-2022-0907, CVE-2022-0908)<\/p>\n
It was discovered that LibTIFF was not properly performing checks to
\navoid division calculations where the denominator value was zero,
\nwhich could lead to an undefined behavior situation via a specially
\ncrafted file. An attacker could possibly use this issue to cause a
\ndenial of service. (CVE-2022-0909)<\/p>\n
It was discovered that LibTIFF was not properly performing bounds
\nchecks, which could lead to an out-of-bounds read via a specially
\ncrafted file. An attacker could possibly use this issue to cause a
\ndenial of service or to expose sensitive information. (CVE-2022-0924)<\/p>\n
It was discovered that LibTIFF was not properly performing the
\ncalculation of data that would eventually be used as a reference for
\nbounds checking operations, which could lead to an out-of-bounds
\nread via a specially crafted file. An attacker could possibly use
\nthis issue to cause a denial of service or to expose sensitive
\ninformation. (CVE-2020-19131)<\/p>\n
It was discovered that LibTIFF was not properly terminating a
\nfunction execution when processing incorrect data, which could lead
\nto an out-of-bounds read via a specially crafted file. An attacker
\ncould possibly use this issue to cause a denial of service or to
\nexpose sensitive information. (CVE-2020-19144)<\/p>\n
It was discovered that LibTIFF was not properly performing checks
\nwhen setting the value for data later used as reference during memory
\naccess, which could lead to an out-of-bounds read via a specially
\ncrafted file. An attacker could possibly use this issue to cause a
\ndenial of service or to expose sensitive information.
\n(CVE-2022-22844)<\/p>\n
