CVE-2017-5078: Google Chrome

High severity, CVSS 8.8. EPSS: 2.8% chance of exploitation in the next 30 days.

Insufficient validation of untrusted input in Blink's mailto: handling in Google Chrome prior to 59.0.3071.86 for Linux, Windows, and Mac allowed a remote attacker to perform command injection via a crafted HTML page, a similar issue to CVE-2004-0121. For example, characters such as * have an incorrect interaction with xdg-email in xdg-utils, and a space character can be used in front of a command-line argument.

Affected products

• Google Chrome: before 59.0.3071.86 (fixed in 59.0.3071.86)
• Red Hat Enterprise Linux Desktop: version 6.0 only
• Red Hat Enterprise Linux Server: version 6.0 only
• Red Hat Enterprise Linux Workstation: version 6.0 only
