Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2013-7205)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform denial of service (DoS) attack.

The vulnerability exists due to a boundary condition when processing a long string in the last key value in the variable list, which triggers a heap-based buffer over-read within the Off-by-one error in the process_cgivars function in contrib/daemonchk.c. A remote attacker can create a specially crafted file, pass it to the application, trigger out-of-bounds read error and crash the affected application.
