[DLA-1589-1] keepalived security update
27 November 2018
===========================================================================
AusCERT Security Bulletin Summary
---------------------------------
Product: keepalived
Publisher: Debian
Operating System: Debian GNU/Linux 8
Linux variants
Impact/Access: Execute Arbitrary Code/Commands -- Remote/Unauthenticated
Denial of Service -- Remote/Unauthenticated
Resolution: Patch/Upgrade
CVE Names: CVE-2018-19115
Original Bulletin:
https://lists.debian.org/debian-lts-announce/2018/11/msg00034.html
Comment: This advisory references vulnerabilities in products which run on
platforms other than Debian. It is recommended that administrators
running keepalived check for an updated version of the software for
their operating system.
While the package listed in the advisory from Debian is "icecast2" we
believe this is a mistake and should be "keepalived".

Package : icecast2
Version : 1:1.2.13-1+deb8u1
CVE ID : CVE-2018-19115
Debian Bug : 914393
keepalived has a heap-based buffer overflow when parsing HTTP status
codes resulting in DoS or possibly unspecified other impact, because
extract_status_code in lib/html.c has no validation of the status code
and instead writes an unlimited amount of data to the heap.
For Debian 8 "Jessie", this problem has been fixed in version
1:1.2.13-1+deb8u1.
We recommend that you upgrade your keepalived packages.
