Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Memory corruption
EUVDB-ID: #VU10569
Risk: High
CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-14632
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to freeing uninitialized memory in the function vorbis_analysis_headerout() in info.c when vi->channels<=0. A remote attacker can supply specially crafted files, trigger memory corruption and execute arbitrary code with elevated privileges.
Update the affected packages.

2) Out-of-bounds read
EUVDB-ID: #VU10571
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-2017-14633
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the function mapping0_forward() in mapping0.c due to out-of-bounds array read. A remote attacker can send the specially crafted audio file, trick the victim into operating it with vorbis_analysis() and cause the application to crash.
Update the affected packages.
