Summary
It was discovered that zlib incorrectly handled pointer arithmetic. An attacker
could use this issue to cause zlib to crash, resulting in a denial of
service, or possibly execute arbitrary code. (CVE-2016-9840, CVE-2016-9841)
It was discovered that zlib incorrectly handled vectors involving left shifts of
negative integers. An attacker could use this issue to cause zlib to
crash, resulting in a denial of service, or possibly execute arbitrary code.
(CVE-2016-9842)
It was discovered that zlib incorrectly handled vectors involving big-endian CRC
calculation. An attacker could use this issue to cause zlib to crash,
resulting in a denial of service, or possibly execute arbitrary code.
(CVE-2016-9843)
