Description
This security bulletin contains information about 4 vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2017-7585)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/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 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)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/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 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)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/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 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)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/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 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.
