Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU32684
Risk: Medium
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-2013-2020
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows remote attackers to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (crash) via a skewed offset larger than the size of the PE section in a UPX packed executable, which triggers an out-of-bounds read.
MitigationUpdate the affected packages.
