[ASA-201711-39] procmail: arbitrary code execution
Arch Linux Security Advisory ASA-201711-39 ========================================== 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 Summary ======= The package procmail before version 3.22-9 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 3.22-9. # pacman -Syu "procmail>=3.22-9" The problem has been fixed upstream but no release is available yet. Workaround ========== None. Description =========== 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. Impact ====== 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.
