Detailsinfo

A vulnerability classified as critical was found in GNU Mailutils 0.5/0.6. This vulnerability affects the function fetch_io. The manipulation of the argument END with an unknown input leads to a heap-based overflow vulnerability. The CWE definition for the vulnerability is CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Integer overflow in the fetch_io function of the imap4d server in GNU Mailutils 0.5 and 0.6, and other versions before 0.6.90, allows remote attackers to execute arbitrary code via a partial message request with a large value in the END parameter, which leads to a heap-based buffer overflow.
