IBM has announced a release for IBM Security Identity Governance and Intelligence (IGI) in response to address multiple security vulnerabilities. The libssh2 packages that implement the SSH2 protocol is affected by four vulnerabilities.

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&gt; for the current score
CVSS Environmental Score*: Undefined
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&gt; for the current score

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.
