Vulnerability Details
CVEID: CVE-2019-3855
DESCRIPTION: libssh2 could allow a remote attacker to execute arbitrary code on
the system, caused by an integer overflow in transport read. By sending
specially crafted packets, a remote attacker could exploit this vulnerability
to trigger an out-of-bounds read and execute arbitrary code on the client
system.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
158339 for the current score
CVSS Environmental Score*: Undefined

CVEID: CVE-2019-3856
DESCRIPTION: libssh2 could allow a remote attacker to execute arbitrary code on
the system, caused by an integer overflow in keyboard interactive handling. By
sending a specially crafted request, a remote attacker could exploit this
vulnerability to trigger an out-of-bounds write and execute arbitrary code on
the client system.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/

CVEID: CVE-2019-3857
DESCRIPTION: libssh2 could allow a remote attacker to execute arbitrary code on
the system, caused by an integer overflow. By sending a specially crafted
SSH_MSG_CHANNEL_REQUEST packet with an exit signal message, a remote attacker
could exploit this vulnerability to trigger an out-of-bounds write and execute
arbitrary code on the client system.

DESCRIPTION: libssh2 could allow a remote attacker to execute arbitrary code on
the system, caused by an integer overflow in user authenticate keyboard
interactive. By sending a specially crafted message, a remote attacker could
exploit this vulnerability to trigger an out-of-bounds write and execute
arbitrary code on the client system.
