Kevin J. McCarthyによる報告:

$imap_check_subscribedまたはブラウザメニューの<subscribe>関数を介して、IMAPメールボックスに「サブスクライブ」する際のリモートコードインジェクションの脆弱性を修正します。Muttは「mailboxes」コマンドを生成し、muttrcパーサーに送信していました。
ただし、「`」をエスケープしていませんでした。これにより、コードが実行され、結果が挿入されます。これにより、悪意のあるIMAPサーバーが任意のコードを実行する可能性があります（$imap_check_subscribedの場合）。

POP本体キャッシングパストラバーサルの脆弱性を修正します。

IMAPヘッダーキャッシングパストラバーサルの脆弱性を修正します。

Several vulnerabilities were discovered in Mutt, a text-based mailreader supporting MIME, GPG, PGP and threading, potentially leading to code execution, denial of service or information disclosure when connecting to a malicious mail/NNTP server.

The remote host is affected by the vulnerability described in GLSA-201810-07 (Mutt, NeoMutt: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mutt, and NeoMutt.
      Please review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to open a specially crafted mail       message or connect to malicious mail server using Mutt or NeoMutt,       possibly resulting in execution of arbitrary code or directory traversal       with the privileges of the process or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. pop.c mishandles a zero-     length UID. (CVE-2018-14356)

Note that Nessus relies on the presence of the package as reported by the vendor.

This update for mutt fixes the following issues :

Security issues fixed :

bsc#1101428: Mutt 1.10.1 security release update.

CVE-2018-14361: Fix that nntp.c proceeds even if memory allocation fails for messages data (bsc#1101568).

Bug fixes: mutt reports as neomutt and incorrect version (bsc#1094717)

No sidebar available in mutt 1.6.1 from Tumbleweed snapshot 20160517 (bsc#980830)

mutt-1.6.1 unusable when built with --enable-sidebar (bsc#982129)
