Debian Security Advisory 5419-1

Debian Linux Security Advisory 5419-1 - Two vulnerabilities were discovered in c-ares, an asynchronous name resolver library.

CVE-2023-31130: Release 1.19.1 · c-ares/c-ares

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.
