Описание
A flaw was found in libarchive. On 32-bit systems, an integer overflow vulnerability exists in the zisofs block pointer allocation logic. A remote attacker can exploit this by providing a specially crafted ISO9660 image, which can lead to a heap buffer overflow. This could potentially allow for arbitrary code execution on the affected system.
Отчет
Important: An integer overflow flaw in libarchive on 32-bit systems can lead to a heap buffer overflow. This vulnerability occurs when processing a specially crafted ISO9660 image, allowing an attacker to potentially execute arbitrary code. Red Hat Enterprise Linux 64-bit systems are not affected by this flaw.
Меры по смягчению последствий
To mitigate this issue, avoid processing untrusted ISO9660 images with applications that utilize libarchive. Users should only extract or read content from ISO images obtained from trusted sources.
