Vulnerability Details

CVEID: CVE-2019-3863 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.
CVSS Base Score: 7.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/158347&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-2019-3857 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
