Title
Libtiff: libtiff write-what-where
Summary
A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file.
By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.

A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.

This vulnerability is a \"write-what-where\" condition, triggered when the library processes a specially crafted TIFF image file.\n\nBy providing an abnormally large image height value in the file\u0027s metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.",

Threats
Impact
Important
A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.

This vulnerability is a \"write-what-where\" condition, triggered when the library processes a specially crafted TIFF image file.\n\nBy providing an abnormally large image height value in the file\u0027s metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.",

Vulnerability from csaf_redhat - Published: 2025-11-11 19:21 - Updated: 2026-04-20 21:32Summary
Red Hat Security Advisory: libtiff security update
Severity
Important
Notes
Topic: An update for libtiff is now available for Red Hat Enterprise Linux 10.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.
Security Fix(es):
* libtiff: Libtiff Write-What-Where (CVE-2025-9900)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Terms of Use: This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/). If you distribute this content, or a modified version of it, you must provide attribution to Red Hat Inc. and provide a link to the original.
A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.

This vulnerability is a \"write-what-where\" condition, triggered when the library processes a specially crafted TIFF image file.\n\nBy providing an abnormally large image height value in the file\u0027s metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.",

Vulnerability from csaf_redhat - Published: 2025-11-12 02:41 - Updated: 2026-04-20 21:32Summary
Red Hat Security Advisory: libtiff security update
Severity
Important
Notes
Topic: An update for libtiff is now available for Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.6 Update Services for SAP Solutions, and Red Hat Enterprise Linux 8.6 Telecommunications Update Service.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.
Security Fix(es):
* libtiff: Libtiff Write-What-Where (CVE-2025-9900)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.

This vulnerability is a \"write-what-where\" condition, triggered when the library processes a specially crafted TIFF image file.\n\nBy providing an abnormally large image height value in the file\u0027s metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.",

Vulnerability from csaf_redhat - Published: 2025-11-12 02:34 - Updated: 2026-04-20 21:33Summary
Red Hat Security Advisory: libtiff security update
Severity
Important
Notes
Topic: An update for libtiff is now available for Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support and Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.
Security Fix(es):
* libtiff: Libtiff Write-What-Where (CVE-2025-9900)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Terms of Use: This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/). If you distribute this content, or a modified version of it, you must provide attribution to Red Hat Inc. and provide a link to the original.
A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.
8.8 (High)

A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.
8.8 (High)

A flaw was found in libtiff. The `get_histogram` function in `file/tiffmedian.c` exhibits a use-after-free condition when processing a specially crafted file, allowing a local attacker to trigger memory corruption. This manipulation results in a use-after-free vulnerability, and can lead to a denial of service.

Threats
Impact
Important
A flaw was found in libtiff. The `setrow` function in `file tools/thumbnail.c` contains a buffer overflow vulnerability triggered by manipulation of image data, which can allow a local attacker to cause a denial of service. This overflow occurs when processing a crafted file. The vulnerability stems from insufficient bounds checking during row data assignment.

Threats
Impact
Important
A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.

This vulnerability is a \"write-what-where\" condition, triggered when the library processes a specially crafted TIFF image file.\n\nBy providing an abnormally large image height value in the file\u0027s metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.",

Vulnerability from csaf_redhat - Published: 2025-11-17 11:38 - Updated: 2026-04-20 21:32Summary
Red Hat Security Advisory: libtiff security update
Severity
Important
Notes
Topic: An update for libtiff is now available for Red Hat Enterprise Linux 9.0 Update Services for SAP Solutions.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.
Security Fix(es):
* libtiff: Libtiff Write-What-Where (CVE-2025-9900)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Terms of Use: This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/). If you distribute this content, or a modified version of it, you must provide attribution to Red Hat Inc. and provide a link to the original.
A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.

This vulnerability is a \"write-what-where\" condition, triggered when the library processes a specially crafted TIFF image file.\n\nBy providing an abnormally large image height value in the file\u0027s metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.",

Threats
Impact
Important
A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.

This vulnerability is a \"write-what-where\" condition, triggered when the library processes a specially crafted TIFF image file.\n\nBy providing an abnormally large image height value in the file\u0027s metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.",

A flaw was found in libtiff. The `get_histogram` function in `file/tiffmedian.c` exhibits a use-after-free condition when processing a specially crafted file, allowing a local attacker to trigger memory corruption. This manipulation results in a use-after-free vulnerability, and can lead to a denial of service.

Threats
Impact
Important
A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.
