CVE-2015-8879 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The odbc_bindcols function in ext/odbc/php_odbc.c in PHP before 5.6.12 mishandles driver behavior for SQL_WVARCHAR columns, which allows remote attackers to cause a denial of service (application crash) in opportunistic circumstances by leveraging use of the odbc_fetch_array function to access a certain type of Microsoft SQL Server table.. EPSS estimates a 3.42% chance of exploitation in the next 30 days.
