Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Integer overflow
EUVDB-ID: #VU17768
Risk: Low
CVSSv3.1: 6.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:P/RL:U/RC:C]
CVE-ID: CVE-2019-8354
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in lsx_make_lpf in effect_i_dsp.c when handling malicious input. A remote attacker can trick the victim into executing a file that submits malicious input to the targeted system with the sox command, trigger a heap-based buffer overflow condition and perform a denial of service (DoS) attack.
MitigationUpdate the affected packages.

2) Integer overflow
EUVDB-ID: #VU17769
Risk: Low
CVSSv3.1: 6.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:P/RL:U/RC:C]
CVE-ID: CVE-2019-8355
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in xmalloc.h when handling malicious input. A remote attacker can trick the victim into executing a file that submits malicious input to the targeted system with the sox command, trigger a heap-based buffer overflow condition channels_start in remix.c and perform a denial of service (DoS) attack.

3) Stack-based buffer overflow
EUVDB-ID: #VU17767
Risk: Low
CVSSv3.1: 6.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:P/RL:U/RC:C]
CVE-ID: CVE-2019-8356
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper protection on an argument passed to the bitrv2 function, as defined in the fft4g.c source code file of the affected software. A remote attacker can trick the victim into executing a file that submits malicious input to the targeted system with the sox command, trigger a stack-based buffer overflow condition and perform a denial of service (DoS) attack.

CVSSv3.1: 6.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:P/RL:U/RC:C]
CVE-ID: CVE-2019-8357
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in n the lsx_make_lpf function, as defined in the effect_i_dsp.c source code file.
