GSD-2015-5147
Vulnerability from gsd - Updated: 2015-06-22 00:00Details
redcarpet Gem for Ruby contains a flaw that allows a stack overflow.
This flaw exists because the header_anchor() function in html.c uses
variable length arrays (VLA) without any range checking. This may
allow a remote attacker to execute arbitrary code.
