3) Out-of-bounds read
EUVDB-ID: #VU54624
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-22918
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in uv__idna_toascii() function in libuv, which is used to convert strings to ASCII. A remote attacker can force the application to resolve a specially crafted hostname, trigger an out-of-bounds read error and gain access to sensitive information or perform a denial of service (DoS) attack.
