CVE-2025-61144
Description
A denial of service flaw has been found in libtiff. This stack-based buffer overflow occurs in tiffcrop (part of libtiff) within the function readSeparateStripsIntoBuffer. When processing a malformed TIFF directory (e.g., improper tags/order, missing StripByteCounts), the function overflows a stack-allocated array (srcbuffs) by accessing one element beyond its boundary in combineSeparateSamplesBytes. This leads to an AddressSanitizer-detected buffer over-read and crash.
Statement
Red Hat employs StackGuard protections which limit the impact of this vulnerability to a denial of service. An out of bounds read in libtiff on a Red Hat system may cause a process termination, but does not pose further risk.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of a program's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the program into an infinite loop.
