Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
EUVDB-ID: #VU21792
Risk: High
CVSSv4.0: 8.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]
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
CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Green]
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 updates from vendor's website.
