Description Andrej Nemec 2017-04-05 12:11:37 UTC 
The ourWriteOut function in tool_writeout.c in curl might allow physically proximate attackers to obtain sensitive information from process memory in opportunistic circumstances by reading a workstation screen during use of a --write-out argument ending in a '%' character, which leads to a heap-based buffer over-read.
