Description
This security bulletin contains information about 4 vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2018-13139)
CWE-ID: CWE-121 - Stack-based buffer overflow
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 unauthenticated attacker to cause DoS condition on the target system.
The weakness exists due to stack-based buffer overflow in psf_memset in common.c. A remote attacker can send a specially crafted audio file, trick the victim into opening it, trigger memory corruption and cause the service to crash.
2) NULL pointer dereference (CVE-ID: CVE-2018-19432)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to NULL pointer dereference in the function sf_write_int in sndfile.c. A remote attacker can trigger NULL pointer dereference and cause the service to crash.
3) Out-of-bounds read (CVE-ID: CVE-2018-19758)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer overread condition in the wav_write_headerfunction, as defined in the wav.c source code file. A remote attacker can trick the victim into following a custom link or opening a crafted audio file that submits malicious input, trigger memory corruption and perform a denial of service attack.
4) Heap-based buffer overflow (CVE-ID: CVE-2021-3246)
CWE-ID: CWE-122 - Heap-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 vulnerability exists due to a boundary error msadpcm_decode_block() function of libsndfile. A remote attacker can trick the victim to open a specially crafted WAV file, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
