Description
This security bulletin contains information about 1 vulnerability.
1) Buffer over-read (CVE-ID: CVE-2013-7290)
CWE-ID: CWE-126 - Buffer over-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 cause DoS condition on the target system.
The weakness exists in the do_item_get function in items.c due to boundary error when running in verbose mode. A remote attacker can cause the service to crash via a request to delete a key, which does not account for the lack of a null terminator in the key and triggers buffer over-read when printing to stderr.
Remediation
