The following vulnerabilities in libssh2 have been addressed by IBM Integrated Management Module II (IMM2).
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.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/158341 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H)
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/158340 for the current score.

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 Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H)
CVEID:CVE-2019-3859
**DESCRIPTION:**libssh2 is vulnerable to a denial of service, caused by an out-of-bounds read in the _libssh2_packet_require and _libssh2_packet_requirev functions. By sending a specially crafted packet, a remote attacker could exploit this vulnerability to cause a denial of service or read data in the client memory.
CVSS Base score: 5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/158343 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:L)
CVEID:CVE-2019-3858
**DESCRIPTION:**libssh2 is vulnerable to a denial of service, caused by an out-of-bounds read. By sending a specially crafted SFTP packet, a remote attacker could exploit this vulnerability to cause a denial of service or read data in the client memory.
CVSS Base score: 5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/158342 for the current score.

CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H)
CVEID:CVE-2019-3862
**DESCRIPTION:**libssh2 is vulnerable to a denial of service, caused by an out-of-bounds read when parsing packets with an exit status message and no payload. By sending specially crafted SSH_MSG_CHANNEL_REQUEST packets, a remote attacker could exploit this vulnerability to cause a denial of service or read data in the client memory.
CVSS Base score: 7.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/158346 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID:CVE-2019-3861
**DESCRIPTION:**libssh2 is vulnerable to a denial of service, caused by an out-of-bounds read when parsing packets with a padding length value greater than the packet length. By sending a specially crafted SSH packet, a remote attacker could exploit this vulnerability to cause a denial of service or read data in the client memory.
CVSS Base score: 5
