Description:
Two vulnerabilities have been reported in Pine, which can be exploited by malicious people to compromise a user's system.
The first vulnerability is caused due to a boundary error when parsing the "message/external-body" type. The problem is that the size of the longest attribute isn't checked, which can result in a buffer overflow if the name is longer than 20K.
The second vulnerability is caused due to an integer overflow in the "rfc2231_get_param()" function when parsing email headers.
Both vulnerabilities can be exploited by sending a specially crafted email to a user, which will execute arbitrary code on the system when opened.
The vulnerabilities affect versions 4.56 and earlier.
Solution:
Update to version 4.58:
