Debian LTS Advisory DLA-3471-1 [email protected]

Package : c-ares
Version : 1.14.0-1+deb10u3
CVE ID : CVE-2023-31130 CVE-2023-32067
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 length of 0 as a graceful shutdown of the connection, which
could cause a denial of service.
For Debian 10 buster, these problems have been fixed in version
1.14.0-1+deb10u3.
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:
https://security-tracker.debian.org/tracker/c-ares
