Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Stack-based buffer overflow (CVE-ID: CVE-2017-7585)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to an error in the "flac_buffer_copy()" function (flac.c). A remote attacker can send a specially crafted FLAC file, trick the victim into opening it, trigger stack-based buffer overflow and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in system compromise.

2) Stack-based buffer overflow (CVE-ID: CVE-2017-7586)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to an error in the "header_read()" function (common.c) when handling ID3 tags. A remote attacker can send a specially crafted FLAC file, trick the victim into opening it, trigger stack-based buffer overflow and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in system compromise.

3) Denial of service (CVE-ID: CVE-2017-7741)

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

The weakness exists due to a write memory access flaw in the flac_buffer_copy function in flac.c. A remote attacker can send a specially crafted FLAC file, trick the victim into opening it, trigger a segmentation violation and cause the application to crash.

Successful exploitation of the vulnerability results in denial of service.

4) Denial of service (CVE-ID: CVE-2017-7742)

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

The weakness exists due to a read memory access flaw in the flac_buffer_copy function in flac.c. A remote attacker can send a specially crafted FLAC file, trick the victim into opening it, trigger a segmentation violation and cause the application to crash.

Successful exploitation of the vulnerability results in denial of service.
