Last modified

CVE-2015-3144 is a vulnerability of currently unknown severity. The fix_hostname function in cURL and libcurl 7.37.0 through 7.41.0 does not properly calculate an index, which allows remote attackers to cause a denial of service (out-of-bounds read or write and crash) or possibly have other unspecified impact via a zero-length host name, as demonstrated by "http://:80" and ":80.". EPSS estimates a 11.03% chance of exploitation in the next 30 days.
