Description
This security bulletin contains information about 12 vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2018-14358)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to stack-based buffer overflow in imap/message.c. A remote attacker can use FETCH response with a long RFC822.SIZE field, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
2) Stack-based buffer overflow (CVE-ID: CVE-2018-14352)
CWE-ID: CWE-121 - Stack-based buffer overflow

The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to imap_quote_string in imap/util.c does not leave room for quote characters. A remote attacker can use FETCH response with a long INTERNALDATE field, trigger stack-based buffer overflow and cause the service to crash.
3) Integer underflow (CVE-ID: CVE-2018-14353)
CWE-ID: CWE-191 - Integer underflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to integer underflow in imap_quote_string in imap/util.c. . A remote attacker can trigger memory corruption and cause the service to crash.
4) Privilege escalation (CVE-ID: CVE-2018-14356)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The vulnerability exists due to improper handling of a zero-length unique identifier (UID) by the pop.c code. A local attacker can manipulate the UID value assigned to an email message and cause the service to crash or execute arbitrary code with elevated privileges.
5) Buffer overflow (CVE-ID: CVE-2018-14359)
CWE-ID: CWE-120 - Buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to buffer overflow when handling malicious input. A remote attacker can use base64 data, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
6) Command injection (CVE-ID: CVE-2018-14354)
CWE-ID: CWE-77 - Command injection
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The vulnerability exists due to command injection. A remote attacker can use IMAP servers to inject and execute arbitrary commands via backquote characters, related to the mailboxes command associated with a manual subscription or unsubscription.
7) Path traversal (CVE-ID: CVE-2018-14355)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to obtain potentially sensitive information cause DoS condition on the target system.
The vulnerability exists due to imap/util.c mishandles ".." directory traversal in a mailbox name. A remote attacker can conduct directory traversal attack and gain access to arbitrary data or cause the service to crash.
8) Path traversal (CVE-ID: CVE-2018-14362)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to obtain potentially sensitive information cause DoS condition on the target system.
The vulnerability exists due to forbid characters that may have unsafe interaction with message-cache pathnames, as demonstrated by a '/' character. A remote attacker can conduct directory traversal attack and gain access to arbitrary data or cause the service to crash.
9) Command injection (CVE-ID: CVE-2018-14357)
CWE-ID: CWE-77 - Command injection
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The vulnerability exists due to command injection. A remote attacker can use IMAP servers to inject and execute arbitrary commands via backquote characters, related to the mailboxes command associated with an automatic subscription.
10) Stack-based buffer overflow (CVE-ID: CVE-2018-14350)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to stack-based buffer overflow in imap/message.c. A remote attacker can use FETCH response with a long INTERNALDATE field, trigger memory corruption and cause the service to crash.

CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to bypass security restrictions on the target system.
The vulnerability exists due to mishandling of a NO response without a message in imap/command.c. A remote attacker can bypass security restrictions and conduct further attacks.
12) Improper input validation (CVE-ID: CVE-2018-14351)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
