Summary
rsync vulnerabilities
Details

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)
