Upgrade Debian:11
glibc
to version 2.19-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream glibc
package and not the glibc
package as distributed by Debian
.
See How to fix?
for Debian:11
relevant fixed versions and status.
The send_dg function in resolv/res_send.c in GNU C Library (aka glibc or libc6) before 2.20 does not properly reuse file descriptors, which allows remote attackers to send DNS queries to unintended locations via a large number of requests that trigger a call to the getaddrinfo function.
