Debian Security Advisory DSA-4488-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
July 25, 2019 https://www.debian.org/security/faq
Package : exim4
CVE ID : CVE-2019-13917
Jeremy Harris discovered that Exim, a mail transport agent, does not
properly handle the ${sort } expansion. This flaw can be exploited by a
remote attacker to execute programs with root privileges in non-default
(and unusual) configurations where ${sort } expansion is used for items
that can be controlled by an attacker.
For the oldstable distribution (stretch), this problem has been fixed
in version 4.89-2+deb9u5.
For the stable distribution (buster), this problem has been fixed in
version 4.92-8+deb10u1.
We recommend that you upgrade your exim4 packages.
For the detailed security status of exim4 please refer to its security
tracker page at:
