The remote host is affected by the vulnerability described in GLSA-201006-16 (GD: User-assisted execution of arbitrary code)
Tomas Hoger reported that the _gdGetColors() function in gd_gd.c does not properly verify the colorsTotal struct member, possibly leading to a buffer overflow.
Impact :
A remote attacker could entice a user to open a specially crafted image file with a program using the GD library, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application, or a Denial of Service condition.
Workaround :
There is no known workaround at this time.
