Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2017-14160)

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

The weakness exists in the bark_noise_hybridmp function in psy.c due to out-of-bounds read. A remote attacker can trick the victim into opening a specially crafted mp4 file and cause the service to crash.

2) Memory corruption (CVE-ID: CVE-2018-10392)

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

The vulnerability exists due to improper validation of the number of channels by mapping0_forward in mapping0.c in Xiph.Org libvorbis. A remote unauthenticated attacker can send a specially crafted file, trigger heap-based buffer overflow or over-read and cause the service to crash.


3) Stack-based buffer over-read (CVE-ID: CVE-2018-10393)

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

The weakness exists in bark_noise_hybridmp in psy.c due to stack-based buffer over-read. A remote attacker can trick the victim into opening a specially crafted file, trigger memory corruption and cause the service to crash.


4) NULL pointer dereference (CVE-ID: CVE-2017-11333)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The vorbis_analysis_wrote function in lib/block.c in Xiph.Org libvorbis 1.3.5 allows remote attackers to cause a denial of service (OOM) via a crafted wav file.


5) Memory corruption (CVE-ID: CVE-2017-14632)

The 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.

6) Out-of-bounds read (CVE-ID: CVE-2017-14633)

The 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.
