The version of python-gevent / grpc installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2020-22217 advisory.

  - Buffer overflow vulnerability in c-ares before 1_16_1 thru 1_17_0 via function ares_parse_soa_reply in     ares_parse_soa_reply.c. (CVE-2020-22217)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Ubuntu 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-6376-1 advisory.

    It was discovered that c-ares incorrectly parsed certain SOA replies. A remote attacker could possibly use     this issue to cause c-res to crash, resulting in a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:7207 advisory.

    The c-ares C library defines asynchronous DNS (Domain Name System) requests and provides name resolving     API.

    Security Fix(es):

    * c-ares: Heap buffer over read in ares_parse_soa_reply (CVE-2020-22217)

    * c-ares: Buffer Underwrite in ares_inet_net_pton() (CVE-2023-31130)

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2023:7207 advisory.

  - Buffer overflow vulnerability in c-ares before 1_16_1 thru 1_17_0 via function ares_parse_soa_reply in     ares_parse_soa_reply.c. (CVE-2020-22217)

  - 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. (CVE-2023-31130)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLED12 / SLED_SAP12 / SLES12 / SLES_SAP12 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2023:3690-1 advisory.
