Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
1) Memory corruption
EUVDB-ID: #VU11550
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-6381
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the zzip_disk_fread function in zzip/mmapped.c due to the size variable is not validated against the amount of file->stored data. A remote attacker can trigger memory corruption and cause the service to crash.
Update the affected package zziplib to version 0.13.69-1.
Vulnerable software versionsArch Linux: All versions
External linkshttp://security.archlinux.org/advisory/ASA-201804-3
Q & A

2) Memory corruption
EUVDB-ID: #VU11551
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-6484
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the __zzip_fetch_disk_trailer function of zzip/zip.c due to memory alignment error and bus error. A remote attacker can submit a specially crafted zip file, trigger memory corruption and cause the service to crash.
Update the affected package zziplib to version 0.13.69-1.
