Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
EUVDB-ID: #VU12202
Risk: High
CVSSv3.1: 8.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-16879
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists in the _nc_write_entry function in tinfo/write_entry.c due to stac-based buffer overflow. A remote attacker can submit a specially crafted terminfo file, as demonstrated by tic, trick the victim into opening it, trigger memory corruption and cause the service to crash or execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.

EUVDB-ID: #VU15935
Risk: Low
CVSSv3.1: 3.4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-19211
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to NULL pointer dereference condition in the _nc_write_entry function when handling maliciou input. A remote attacker can trick the victim into opening a specially crafted file that submits malicious input, trigger a NULL pointer dereference condition and cause the service to crash.

EUVDB-ID: #VU21792
Risk: High
CVSSv3.1: 7.3 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2019-17594
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the "_nc_find_entry" function in "tinfo/comp_hash.c" in the terminfo library. A remote attacker can trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

EUVDB-ID: #VU21793
Risk: Medium
CVSSv3.1: 4.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C]
CVE-ID: CVE-2019-17595
CWE-ID:
CWE-126 - Buffer over-read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer over-read issue in the "fmt_entry" function in "tinfo/comp_hash.c" in the terminfo library. A remote attacker can trigger a buffer over-read condition and cause a denial of service condition on the target system.Install update from vendor's website.
