Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) 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.
Update the affected package nodejs-lts-erbium to version 12.22.3-1.
Vulnerable software versionsArch Linux: All versions
nodejs-lts-erbium: before 12.22.3-1

2) Incorrect Regular Expression
EUVDB-ID: #VU61255
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-2021-23362
CWE-ID:
CWE-185 - Incorrect Regular Expression
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation when processing regular expression "shortcutMatch" in the "fromUrl" function. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
