CVE-2023-31124 (GCVE-0-2023-31124)

Vulnerability from cvelistv5 – Published: 2023-05-25 21:09 – Updated: 2025-02-13 16:49

Title

AutoTools does not set CARES_RANDOM_FILE during cross compilation

Summary

c-ares is an asynchronous resolver library. When cross-compiling c-ares and using the autotools build system, CARES_RANDOM_FILE will not be set, as seen when cross compiling aarch64 android. This will downgrade to using rand() as a fallback which could allow an attacker to take advantage of the lack of entropy by not using a CSPRNG. This issue was patched in version 1.19.1.

Severity

3.7 (Low)

CVE-2023-31130 (GCVE-0-2023-31130)

Vulnerability from cvelistv5 – Published: 2023-05-25 21:45 – Updated: 2025-02-13 16:49

Title

Buffer Underwrite in ares_inet_net_pton()

Summary

c-ares is an asynchronous resolver library. ares_inet_net_pton() is vulnerable to a buffer underflow for certain ipv6 addresses, in particular "0::00:00:00/2" was found to cause an issue. C-ares only uses this function internally for configuration purposes which would require an administrator to configure such an address via ares_set_sortlist(). However, users may externally use ares_inet_net_pton() for other purposes and thus be vulnerable to more severe issues. This issue has been fixed in 1.19.1.

Severity

4.1 (Medium)

CVE-2023-31147 (GCVE-0-2023-31147)

Vulnerability from cvelistv5 – Published: 2023-05-25 21:55 – Updated: 2025-02-13 16:49

Title

Insufficient randomness in generation of DNS query IDs in c-ares

Summary

c-ares is an asynchronous resolver library. When /dev/urandom or RtlGenRandom() are unavailable, c-ares uses rand() to generate random numbers used for DNS query ids. This is not a CSPRNG, and it is also not seeded by srand() so will generate predictable output. Input from the random number generator is fed into a non-compilant RC4 implementation and may not be as strong as the original RC4 implementation. No attempt is made to look for modern OS-provided CSPRNGs like arc4random() that is widely available. This issue has been fixed in version 1.19.1.

Severity

5.9 (Medium)

CVE-2023-32067 (GCVE-0-2023-32067)

Vulnerability from cvelistv5 – Published: 2023-05-25 22:49 – Updated: 2025-02-13 16:50

Title

0-byte UDP payload DoS in c-ares

Summary

c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service. If a target resolver sends a query, the attacker forges a malformed UDP packet with a length of 0 and returns them to the target resolver. The target resolver erroneously interprets the 0 length as a graceful shutdown of the connection. This issue has been patched in version 1.19.1.

Severity

7.5 (High)

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
