Multiple heap buffer overflows in tiffcrop.c utility in libtiff library Version 4.4.0 allows attacker to trigger unsafe or out of bounds memory access via crafted TIFF image file which could result into application crash, potential information disclosure or any other context-dependent impact
A heap-based buffer overflow flaw was found in Libtiff's tiffcrop utility. This issue occurs during the conversion of a TIFF image file, allowing an attacker to pass a crafted TIFF image file to tiffcrop utility, which causes an out-of-bound access resulting an application crash, eventually leading to a denial of service.
Отчет
Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-122: Heap-based Buffer Overflow vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low. Access to the platform is granted only after successful hard token, multi-factor authentication (MFA), which is coupled with least privilege principles to ensure that only authorized roles and users can execute or manipulate code. Red Hat enforces the principle of least functionality, ensuring that only essential features, services, and ports are enabled. This minimizes the number of components that could be affected by heap-based buffer overflow exploitations. The environment leverages malicious code protections such as IPS/IDS and antimalware solutions that detect and respond to indicators in real time, preventing or limiting the impact of exploitation attempts. Static code analysis and peer code review techniques ensure all user inputs are thoroughly validated, preventing improperly validated inputs from causing system instability, exposing sensitive data, or escalating risks. Finally, memory protection mechanisms such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) enhance resilience against memory buffer overflows and denial-of-service attacks.
