zlib vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in zlib
Software Description
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)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 LTS
lib32z1 - 1:1.2.8.dfsg-2ubuntu4.3
lib64z1 - 1:1.2.8.dfsg-2ubuntu4.3
libn32z1 - 1:1.2.8.dfsg-2ubuntu4.3
libx32z1 - 1:1.2.8.dfsg-2ubuntu4.3
zlib1g - 1:1.2.8.dfsg-2ubuntu4.3
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
