Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2018-10360)
The 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.
2) Stack out-of-bounds read (CVE-ID: CVE-2019-8905)
The 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.
3) Out-of-bounds read (CVE-ID: CVE-2019-8906)
The vulnerability allows a remote attacker to obtain potentially sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to out-of-bounds read in the do_core_note function. 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.
4) Stack-based buffer overflow (CVE-ID: CVE-2019-8907)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to stack-based buffer overflow in the do_core_note function. 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 perform a denial of service attack.
