Description

A flaw was found in curl before version 7.51.0 When re-using a connection, curl was doing case insensitive comparisons of user name and password with the existing connections. This means that if an unused connection with proper credentials exists for a protocol that has connection-scoped credentials, an attacker can cause that connection to be reused if s/he knows the case-insensitive version of the correct password.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

v < 7.51.07.51.0
Affected range stops below 7.51.0, so it looks safe — our inference, not a vendor statement
