Name of the Vulnerable Software and Affected Versions libical versions 0.47 through 1.0

Description The issue allows remote attackers to cause a denial of service, specifically an out-of-bounds heap read, by providing a crafted string to the icalparser parse string function, which is processed by the icaltime from string function.
