Description

According to the versions of the dovecot packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- An issue was discovered in Dovecot before 2.3.13. By using IMAP IDLE, an authenticated attacker can trigger unhibernation via attacker-controlled parameters, leading to access to other users' email messages (and path disclosure).(CVE-2020-24386)

- Dovecot before 2.3.13 has Improper Input Validation in lda, lmtp, and imap, leading to an application crash via a crafted email message with certain choices for ten thousand MIME parts.(CVE-2020-25275)
