CVE-2016-7127 (opens in a new tab)How to fix?
There is no fixed version for RHEL:10 php55-php-mysqlnd.
NVD Description
Note: Versions mentioned in the description apply only to the upstream php55-php-mysqlnd package and not the php55-php-mysqlnd package as distributed by RHEL.
See How to fix? for RHEL:10 relevant fixed versions and status.
The imagegammacorrect function in ext/gd/gd.c in PHP before 5.6.25 and 7.x before 7.0.10 does not properly validate gamma values, which allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact by providing different signs for the second and third arguments.
