Package : c-ares
Version : 1.14.0-1+deb10u2
CVE ID : CVE-2022-4904
Debian Bug : 1031525
It was discovered that in c-ares, an asynchronous name resolver library,
the config_sortlist function is missing checks about the validity of the
input string, which allows a possible arbitrary length stack overflow and
thus may cause a denial of service.
For Debian 10 buster, this problem has been fixed in version
1.14.0-1+deb10u2.
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:
