This security bulletin contains information about 5 vulnerabilities.
Updated 19.12.2022
Added vulnerability #5
1) Buffer overflow
EUVDB-ID: #VU61671
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-25032
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when compressing data. A remote attacker can pass specially crafted input to the application, trigger memory corruption and perform a denial of service (DoS) attack.
