Date : 2016-09-30
CVE-ID : CVE-2016-5180
Package : c-ares
Type : arbitrary code execution
Remote : Yes
Link : https://wiki.archlinux.org/index.php/CVE
The package c-ares before version 1.12.0-1 is vulnerable to arbitrary
code execution.
Upgrade to 1.12.0-1.
The problem has been fixed upstream in version 1.12.0.
None.
When a string is passed in to ares_create_query or ares_mkquery and
uses an escaped trailing dot, like โhello.โ, c-ares calculates the
string length wrong and subsequently writes outside of the the
allocated buffer with one byte. The wrongly written byte is the least
significant byte of the โdnsclassโ argument; most commonly 1.
A remote attacker is able to perform a denial of service attack or
possibly execute arbitrary code under certain circumstances.
