  * [[slackware.current>ap/sudo-1.9.5p2-i586-1.txz]] \\   When invoked as sudoedit, the same set of command line options \\   are now accepted as for "sudo -e". The -H and -P options are \\   now rejected for sudoedit and "sudo -e" which matches the sudo \\   1.7 behavior. This is part of the fix for CVE-2021-3156. \\   Fixed a potential buffer overflow when unescaping backslashes \\   in the command's arguments. Normally, sudo escapes special \\   characters when running a command via a shell (sudo -s or sudo \\   -i). However, it was also possible to run sudoedit with the -s \\   or -i flags in which case no escaping had actually been done, \\   making a buffer overflow possible. This fixes CVE-2021-3156. \\   For more information, see: \\     https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-3156 \\   (* Security fix *)
  * [[slackware.current>l/loudmouth-1.5.4-i586-1.txz]]
  * [[slackware.current>n/autofs-5.1.7-i586-1.txz]]
  * [[slackware.current>n/dnsmasq-2.84-i586-1.txz]] \\   This update fixes bugs and remotely exploitable security issues: \\     Use the values of --min-port and --max-port in outgoing \\     TCP connections to upstream DNS servers. \\     Fix a remote buffer overflow problem in the DNSSEC code. Any \\     dnsmasq with DNSSEC compiled in and enabled is vulnerable to this, \\     referenced by CVE-2020-25681, CVE-2020-25682, CVE-2020-25683 \\     CVE-2020-25687. \\     Be sure to only accept UDP DNS query replies at the address \\     from which the query was originated. This keeps as much entropy \\     in the {query-ID, random-port} tuple as possible, to help defeat \\     cache poisoning attacks. Refer: CVE-2020-25684. \\     Use the SHA-256 hash function to verify that DNS answers \\     received are for the questions originally asked. This replaces \\     the slightly insecure SHA-1 (when compiled with DNSSEC) or \\     the very insecure CRC32 (otherwise). Refer: CVE-2020-25685. \\     Handle multiple identical near simultaneous DNS queries better. \\     Previously, such queries would all be forwarded \\     independently. This is, in theory, inefficent but in practise \\     not a problem, _except_ that is means that an answer for any \\     of the forwarded queries will be accepted and cached. \\     An attacker can send a query multiple times, and for each repeat, \\     another {port, ID} becomes capable of accepting the answer he is \\     sending in the blind, to random IDs and ports. The chance of a \\     succesful attack is therefore multiplied by the number of repeats \\     of the query. The new behaviour detects repeated queries and \\     merely stores the clients sending repeats so that when the \\     first query completes, the answer can be sent to all the \\     clients who asked. Refer: CVE-2020-25686. \\   For more information, see: \\     https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-25681 \\     https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-25682 \\     https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-25683 \\     https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-25684 \\     https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-25685 \\     https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-25686 \\     https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-25687 \\   (* Security fix *)

==== Rebuilt ====
