Description
This security bulletin contains information about 1 vulnerability.
1) Integer overflow (CVE-ID: CVE-2018-7568)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the parse_die function that is defined in the dwarf1.c source code file due to the improper processing of crafted Executable and Linkable Format (ELF) files that contain corrupted dwarf1 debug information. A remote attacker can send a specially crafted ELF file, trick the victim into opening it, trigger integer overflow and cause the service to crash.
