Описание
A flaw was found in GIMP. An integer overflow vulnerability exists when processing ICO image files, specifically in the ico_read_info and ico_read_icon functions. This issue arises because a size calculation for image buffers can wrap around due to a 32-bit integer evaluation, allowing oversized image headers to bypass security checks. A remote attacker could exploit this by providing a specially crafted ICO file, leading to a buffer overflow and memory corruption, which may result in an application level denial of service.
Отчет
This MODERATE impact flaw in GIMP allows a remote attacker to cause an application denial of service. The vulnerability occurs due to an integer overflow when processing specially crafted ICO image files, leading to memory corruption. User interaction is required for exploitation, as a malicious ICO file must be opened by the GIMP application.
Меры по смягчению последствий
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.

[ICO import integer overflow bypass leads to heap buffer overflow]
A flaw was found in GIMP. An integer overflow vulnerability exists when processing ICO image files, specifically in the `ico_read_info` and `ico_read_icon` functions. This issue arises because a size calculation for image buffers can wrap around due to a 32-bit integer evaluation, allowing oversized image headers to bypass security checks. A remote attacker could exploit this by providing a specially crafted ICO file, leading to a buffer overflow and memory corruption, which may result in an application level denial of service.
