Description

This security bulletin contains information about 1 vulnerability.


1) Buffer overflow (CVE-ID: CVE-2017-7407)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local non-authenticated attacker to gain access to sensitive information.

The ourWriteOut function in tool_writeout.c in curl 7.53.1 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.
