CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-12375

CWE-ID: CWE-120 - Buffer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to input validation checking mechanisms during parsing the rfc2047 function in mbox. A remote attacker can send a specially crafted input, trigger buffer overflow and cause the service to crash.

Mitigation

Update the affected packages.

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-12374

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to input validation checking mechanisms during parsing mbox.c operations on bounce messages. A remote attacker can send a specially crafted input, trigger use-after-free error and cause the service to crash.

Mitigation

Update the affected packages.

10) Use-after-free error

EUVDB-ID: #VU12172

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-6420

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a rmeote attacker to cause DoS condition on the target system.

The weakness exists in libclamav/wwunpack.c due to use-after-free error. A remote attacker can trick the victim into opening a specially crafted PE file with WWPack compression, trigger memory corruption and cause the service to crash.

Mitigation

Update the affected packages.
