Title: OpenSSH: Permission issue (GLSA 201801-05)
A flaw has been discovered in OpenSSH which could allow a remote
attacker to create zero-length files.
OpenSSH is a complete SSH protocol implementation that includes SFTP
client and server support.
Vulnerable: < 7.5_p1-r3
Unaffected: >= 7.5_p1-r3
Architectures: All supported architectures
The process_open function in sftp-server.c in OpenSSH did not properly
prevent write operations in readonly mode.
A remote attacker could cause the creation of zero-length files.
There is no known workaround at this time.
All OpenSSH users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/openssh-7.5_p1-r3"
