Description
This security bulletin contains information about 1 vulnerability.
1) Data Handling (CVE-ID: CVE-2015-1827)
CWE-ID: CWE-19 - Data Handling
CVSSv4: 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:Green
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The get_user_grouplist function in the extdom plug-in in FreeIPA before 4.1.4 does not properly reallocate memory when processing user accounts, which allows remote attackers to cause a denial of service (crash) via a group list request for a user that belongs to a large number of groups.
Remediation
Install update from vendor's website.
