Adobe issued an out-of-band Flash Player update for Windows, Macintosh, and Linux on Thursday that addresses 18 vulnerabilities, including the company's most recent zero-day exploit.

The addressed bugs could allow an attacker to take control of an affected system, Adobe wrote in its post on the release.

The most recent zero-day exploit, CVE-2015-0313, was also patched in an earlier auto-update on Wednesday. The bug is actively being exploited in the wild via drive-by-download attacks against systems running Internet Explorer and Firefox on Windows 8.1 and below.

All the bugs, except for those affecting Adobe Flash Player and earlier for Linux, were given a priority rating of “1.”

The software updates resolve use-after-free, memory corruption, type confusion, heap buffer overflow and buffer overflow vulnerabilities, all which could lead to code execution. Null point dereference issues were also addressed.
