Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Stack out-of-bounds read
EUVDB-ID: #VU17829
Risk: Low
CVSSv4.0: 2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2019-8904
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to stack-based buffer over-read in the do_core_note function, as defined in the readelf.c source code file. A remote attacker can trick the victim into executing a file that submits malicious input to the targeted system with the file command, trigger memory corruption and gain access to arbitrary data or perform a denial of service attack.
MitigationUpdate the affected package file to version 5.36-1.

2) Stack out-of-bounds read
EUVDB-ID: #VU17821
Risk: Low
CVSSv4.0: 2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2019-8905
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to stack-based buffer over-read in the do_core_note function, related to file_printable. A remote attacker can trick the victim into executing a file that submits malicious input to the targeted system with the file command, trigger memory corruption and gain access to arbitrary data or perform a denial of service attack.
MitigationUpdate the affected package file to version 5.36-1.

5) Out-of-bounds read
EUVDB-ID: #VU13453
Risk: Low
CVSSv4.0: 2.7 [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:Clear]
CVE-ID: CVE-2018-10360
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 vulnerability exists in the do_core_note function in readelf.c in libmagic.a due to an error when processing malicious input. A remote attacker can send a specially crafted crafted ELF file, trigger out-of-bounds read and cause the service to crash.
MitigationUpdate the affected package file to version 5.36-1.
