Description
This security bulletin contains information about 6 vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2018-14679)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a local attacker to cause DoS condition on the target system.
The vulnerability exists due to stack-based buffer overflow the read_chunk function, as defined in the mspack/chmd.c source code file. A local attacker can send a specially crafted request that submits malicious input, trigger memory corruption and cause the service to crash.
2) Infinite loop (CVE-ID: CVE-2023-20197)
CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in the HFS+ file parser. A remote attacker can consume all available system resources and cause denial of service conditions.
3) Input validation error (CVE-ID: CVE-2024-20380)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in the HTML file parser. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
4) Out-of-bounds read (CVE-ID: CVE-2024-20505)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the PDF file parser. A remote attacker can pass a specially crafted PDF file to the antivirus, trigger an out-of-bounds read error and crash the antivirus engine.
5) UNIX symbolic link following (CVE-ID: CVE-2024-20506)
CWE-ID: CWE-61 - UNIX Symbolic Link (Symlink) Following
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to corrupt system files.
The vulnerability exists due to a symlink following issue within the logging module. A local user with existing access to the 'clamd' or 'freshclam' services can corrupt system files and perform a denial of service (DoS) attack.
6) Heap-based buffer overflow (CVE-ID: CVE-2025-20128)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when decrypting OLE2 file format. A remote attacker can pass a specially crafted file to the application, trigger a heap-based buffer overflow and perform a denial of service (DoS) attack.
