Severity: Critical
Date : 2017-11-30
CVE-ID : CVE-2017-16844
Package : procmail
Type : arbitrary code execution
Remote : Yes
Link : https://security.archlinux.org/AVG-515
The package procmail before version 3.22-9 is vulnerable to arbitrary
code execution.
Upgrade to 3.22-9.
The problem has been fixed upstream but no release is available yet.
None.
A heap-based buffer overflow flaw was found in the loadbuf function in
formisc.c in the formail utility in procmail <= 3.22 because of a
hardcoded realloc size. When the buffer is too small, the function
tries to resize it, but only by Bsize (=128) bytes which is not
necessarily enough. A remote attacker could send a specially crafted
email that, when processed by formail, could cause formail to crash or,
possibly, execute arbitrary code as the user running formail.
