Microsoft has released the June edition of its Update (neé Patch) Tuesday security update dump.

This month's bundle includes eight security bulletins, two rated "critical" and six rated "important." Users and administrators are advised to test (if necessary) and install the updates as soon as possible to prevent attacks.

MS15-056 A cumulative patch for Internet Explorer versions 6-11. It addresses 24 CVE-listed security flaws. Rated "critical" for remote code execution risks, but Windows Server installations are considered a lower risk as IE is rarely used with those systems. Discovery was credited to 16 researchers, including members of the HP ZeroDay Initiative, NSFOCUS Security Team and Palo Alto Networks.

MS15-057 A Windows update to address a single flaw in Media Player for Windows Vista and 7 and Windows Server 2003 through 2008 R2. Opening a web page that plays a maliciously crafted video will trigger the bug, which can be exploited to hijack the PC. The bulletin is rated "critical" for remote code execution. Microsoft credited someone called bilou in spotting the vulnerability.

Infosec biz Shavlik's Chris Goettl told The Reg today that there seems to be at least one patch missing from Tuesday's batch.

"June patches are just releasing and there is a placeholder, but currently there is no MS15-058 bulletin, which is interesting," Goettl said. "We will have to wait and see if anything comes of this, such as an out of band or a late drop."

Adobe is also releasing a scheduled security update. Their patch addresses 13 CVE-listed vulnerabilities in Flash Player for Windows, OS X and Linux systems. The update is being listed as a top priority for all three platforms. Users running AIR Desktop Runtime, AIR SDK and AIR for Android should also update, though those are considered to be a lower risk. ®
