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.
MitigationUpdate the affected package ncurses to the latest version.

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.Update the affected package ncurses to the latest version.
