Description:	Summary: The remote host is missing an update for the Debian 'c-ares' package(s) announced via the DSA-5419-1 advisory. Vulnerability Insight: Two vunerabilities were discovered in c-ares, an asynchronous name resolver library: CVE-2023-31130 ares_inet_net_pton() is found to be 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, however external usage for other purposes may cause more severe issues. CVE-2023-32067 Target resolver may erroneously interprets a malformed UDP packet with a lenght of 0 as a graceful shutdown of the connection, which could cause a denial of service. For the stable distribution (bullseye), these problems have been fixed in version 1.17.1-1+deb11u3. We recommend that you upgrade your c-ares packages. For the detailed security status of c-ares please refer to its security tracker page at: [link moved to references] Affected Software/OS: 'c-ares' package(s) on Debian 11.
