net/url: Incorrect parsing of IPv6 host literals in net/url

The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...

The vulnerability of the Rack module in the Ruby programming language involves the use of a regular expression c, which has an inefficient computational cost. This allows attackers to trigger a service failure.

The vulnerability of the Ruby interpreter’s Rack module is related to the incorrect handling of invalid URL addresses. Exploiting this vulnerability can allow a remote attacker to cause service interruptions...
