Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Memory corruption
EUVDB-ID: #VU10569
Risk: High
CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
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 package libvorbis to version 1.3.6-1.
Vulnerable software versionsArch Linux: All versions

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Out-of-bounds read
EUVDB-ID: #VU10571
Risk: Low
CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
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 package libvorbis to version 1.3.6-1.

3) Buffer overflow
EUVDB-ID: #VU11140
Risk: High
CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2018-5146
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when processing Vorbis audio within libvorbis library. A remote unauthenticated attacker can create a specially crafted HTML page, trick the victim into opening it, trigger out-of-bounds write and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected package libvorbis to version 1.3.6-1.
