Vulnerability Details

Summary

IBM Chassis Management Module (CMM) has addressed the following vulnerabilities in Ncurses.

Vulnerability Details

CVEID: CVE-2017-13731

Description: Ncurses is vulnerable to a denial of service, caused by an illegal address access in the postprocess_termcap function in parse_entry.c. By using a specially-crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.

CVSS Base Score: 3.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/131059 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)

CVEID: CVE-2017-13730

Description: Ncurses is vulnerable to a denial of service, caused by an illegal address access in the _nc_read_entry_source function in progs/tic.c. By using a specially-crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.

CVSS Base Score: 3.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/131057> for the current score
