Name of the Vulnerable Software and Affected Versions libcroco version 0.6.12

Description The issue is related to the cr tknzr parse comment function in the cr-tknzr.c component of the libcroco library, which can cause a denial of service due to a memory allocation error when processing a crafted CSS file.
