Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU76424
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2023-31124
CWE-ID:
CWE-338 - Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to an error when cross-compiling c-ares and using the autotools build system. As a result, the CARES_RANDOM_FILE is not be set, which results in usage of a rand() function as a fallback, leading to weak entropy.
Install update from vendor's website.

CVE-ID: CVE-2023-31130
CWE-ID:
CWE-124 - Buffer Underwrite ('Buffer Underflow')
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a buffer underflow when using certain IPv6 addresses, such as 0::00:00:00/2". A local privileged user can trigger a boundary error and crash the service.

EUVDB-ID: #VU76426
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2023-31147
CWE-ID:
CWE-338 - Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to usage of a rand() function in case /dev/urandom or RtlGenRandom() are unavailable. A remote attacker can perform spoofing attack.
