Summary

Multiple libarchive vulnerabilities affect Watson Explorer.

Vulnerability Details

CVEID: CVE-2017-14166
DESCRIPTION: libarchive is vulnerable to a denial of service, caused by a
xml_data heap-based buffer over-read issue in the atol8 function in
archive_read_support_format_xar.c. By persuading a victim to open a
specially-crafted file, a remote attacker could exploit this vulnerability to
cause the application to crash.
CVSS Base Score: 5.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
131555 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:H)

CVEID: CVE-2017-14501
DESCRIPTION: libarchive is vulnerable to a heap-based buffer overflow, caused
by improper bounds checking by the parse_file_info function in
archive_read_support_format_iso9660.c. By persuading a victim to extract a
specially-crafted iso file, a remote attacker could overflow a buffer and
execute arbitrary code on the system.
CVSS Base Score: 7.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
132122 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID: CVE-2017-14502
DESCRIPTION: libarchive is vulnerable to a buffer overflow, caused by improper
bounds checking by the read_header function in
archive_read_support_format_rar.c. By persuading a victim to open a
specially-crafted RAR file, a remote attacker could overflow a buffer and
execute arbitrary code on the system.
CVSS Base Score: 7.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
132123 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID: CVE-2017-14503
DESCRIPTION: libarchive is vulnerable to a heap-based buffer overflow, caused
by improper bounds checking by the lha_read_data_none function in
archive_read_support_format_lha.c. By persuading a victim to extract a
specially-crafted lha archive, a remote attacker could overflow a buffer and
execute arbitrary code on the system.
CVSS Base Score: 7.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
132124 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)
