Description Thomas Deutschmann (RETIRED) gentoo-dev 2018-02-26 17:24:32 UTC
Incoming details.
Comment 1 Thomas Deutschmann (RETIRED) gentoo-dev 2018-02-28 22:18:20 UTC
 * CVE-2017-15130: TLS SNI config lookups may lead to excessive
   memory usage, causing imap-login/pop3-login VSZ limit to be reached
   and the process restarted. This happens only if Dovecot config has
   local_name { } or local { } configuration blocks and attacker uses
   randomly generated SNI servernames.
 * CVE-2017-14461: Parsing invalid email addresses may cause a crash or
   leak memory contents to attacker. For example, these memory contents
   might contain parts of an email from another user if the same imap
   process is reused for multiple users. First discovered by Aleksandar
   Nikolic of Cisco Talos. Independently also discovered by "flxflndy"
   via HackerOne.

@maintainer(s), 2.2.19 needs to be purged as it is vulnerable and sh is not a stable arch.

sparc has been removed from cc as it has no other stable keywords for previous versions.
