Security updates released by Adobe on Tuesday patch seven vulnerabilities in Flash Player and one vulnerability in Shockwave Player.
Flash Player 126.96.36.199 fixes critical security holes that affect version 188.8.131.52 and earlier on Windows, Mac, Linux and Chrome OS. Adobe has found no evidence of exploitation in the wild.
The vulnerabilities include buffer overflow, use-after-free and other memory corruption issues that can lead to arbitrary code execution. The latest version also addresses an information disclosure problem related to a random number generator.
The weaknesses were reported to Adobe by researchers at Qihoo 360, Palo Alto Networks, the Nanyang Technological University in Singapore, and an expert who wanted to remain anonymous.
In the case of Shockwave Player, version 184.108.40.206 for Windows patches an important privilege escalation flaw (CVE-2017-2983) related to the directory search path used to find resources.
The flaw was disclosed responsibly by Nitesh Shilpkar and there is no evidence that it has been exploited for malicious purposes.
Last month, Adobe patched more than a dozen code execution vulnerabilities in Flash Player, and several other bugs in Digital Editions and the Campaigns marketing tool.
