Publication date: 29 Feb 2020
URL: https://advisories.mageia.org/MGASA-2020-0108.html
Type: security
Affected Mageia releases: 7
CVE: CVE-2016-9840,
     CVE-2016-9841,
     CVE-2016-9842,
     CVE-2016-9843

Updated rsync packages fix security vulnerabilities:

It was discovered that rsync incorrectly handled pointer arithmetic in
zlib. An attacker could use this issue to cause rsync to crash, resulting
in a denial of service, or possibly execute arbitrary code (CVE-2016-9840,
CVE-2016-9841)

It was discovered that rsync incorrectly handled vectors involving left
shifts of negative integers in zlib. An attacker could use this issue to
cause rsync to crash, resulting in a denial of service, or possibly
execute arbitrary code (CVE-2016-9842).

It was discovered that rsync incorrectly handled vectors involving big-
endian CRC calculation in zlib. An attacker could use this issue to cause
rsync to crash, resulting in a denial of service, or possibly execute
arbitrary code (CVE-2016-9843).

Please note, we now compile against system zlib. If rsync fails to sync
with older remote systems using compression (-z), you have either update
the remote host to a newer version or disable compression.
