Описание
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to ImageMagick versions 6.9.13-28 and 7.1.2-2, a format string bug vulnerability exists in InterpretImageFilename function where user input is directly passed to FormatLocaleString without proper sanitization. An attacker can overwrite arbitrary memory regions, enabling a wide range of attacks from heap overflow to remote code execution. This issue has been patched in versions 6.9.13-28 and 7.1.2-2.
A flaw was found in ImageMagick. Processing a file with a specially crafted name, specifically one with format specifiers such as %d, %o, or %x, can trigger a format string bug due to improper input sanitization, resulting in a heap-based buffer over-read or arbitrary code execution.
Отчет
This issue can cause a heap-based buffer over-read or arbitrary code execution via a crafted filename. However, default Red Hat Enterprise Linux security features such as SELinux enforcement, Address Space Layout Randomization (ASLR) and memory protections reduce the possibility of exploitation, limiting the impact to a denial of service. Additionally, ImageMagick is not shipped in Red Hat Enterprise Linux 8, 9 and 10. Therefore, these versions are not affected by this vulnerability.
Меры по смягчению последствий
To prevent unintended interpretation of the filename as a format string, users can explicitly disable format string parsing by defining the filename as a literal. This can be done using the following directive: In wrappers: filename:literal From the command line: -define filename:literal=true
