| CVE-2021-21424 | 2 Fedoraproject, Sensiolabs | 2 Fedora, Symfony | 2021-06-01 | 5.0 MEDIUM | 5.3 MEDIUM |
| Symfony is a PHP framework for web and console applications and a set of reusable PHP components. The ability to enumerate users was possible without relevant permissions due to different handling depending on whether the user existed or not when attempting to use the switch users functionality. We now ensure that 403s are returned whether the user exists or not if a user cannot switch to a user or if the user does not exist. The patch for this issue is available for branch 3.4. | |||||
| CVE-2021-21228 | 3 Debian, Fedoraproject, Google | 3 Debian Linux, Fedora, Chrome | 2021-06-01 | 4.3 MEDIUM | 4.3 MEDIUM |
| Insufficient policy enforcement in extensions in Google Chrome prior to 90.0.4430.93 allowed an attacker who convinced a user to install a malicious extension to bypass navigation restrictions via a crafted Chrome Extension. | |||||
| CVE-2021-21229 | 3 Debian, Fedoraproject, Google | 4 Debian Linux, Fedora, Android and 1 more | 2021-06-01 | 4.3 MEDIUM | 6.5 MEDIUM |
| Incorrect security UI in downloads in Google Chrome on Android prior to 90.0.4430.93 allowed a remote attacker to perform domain spoofing via a crafted HTML page. | |||||
| CVE-2019-14847 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Samba | 2021-05-29 | 4.0 MEDIUM | 4.9 MEDIUM |
| A flaw was found in samba 4.0.0 before samba 4.9.15 and samba 4.10.x before 4.10.10. An attacker can crash AD DC LDAP server via dirsync resulting in denial of service. Privilege escalation is not possible with this issue. | |||||
| CVE-2019-14907 | 5 Canonical, Fedoraproject, Redhat and 2 more | 9 Ubuntu Linux, Fedora, Enterprise Linux and 6 more | 2021-05-29 | 2.6 LOW | 6.5 MEDIUM |
| All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with "log level = 3" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless). | |||||
| CVE-2019-10218 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2021-05-29 | 4.3 MEDIUM | 6.5 MEDIUM |
| A flaw was found in the samba client, all samba versions before samba 4.11.2, 4.10.10 and 4.9.15, where a malicious server can supply a pathname to the client with separators. This could allow the client to access files and folders outside of the SMB network pathnames. An attacker could use this vulnerability to create files outside of the current working directory using the privileges of the client user. | |||||
| CVE-2019-14870 | 3 Canonical, Fedoraproject, Samba | 3 Ubuntu Linux, Fedora, Samba | 2021-05-29 | 6.4 MEDIUM | 5.4 MEDIUM |
| All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the S4U (MS-SFU) Kerberos delegation model includes a feature allowing for a subset of clients to be opted out of constrained delegation in any way, either S4U2Self or regular Kerberos authentication, by forcing all tickets for these clients to be non-forwardable. In AD this is implemented by a user attribute delegation_not_allowed (aka not-delegated), which translates to disallow-forwardable. However the Samba AD DC does not do that for S4U2Self and does set the forwardable flag even if the impersonated client has the not-delegated flag set. | |||||
| CVE-2019-14833 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Samba | 2021-05-29 | 4.9 MEDIUM | 5.4 MEDIUM |
| A flaw was found in Samba, all versions starting samba 4.5.0 before samba 4.9.15, samba 4.10.10, samba 4.11.2, in the way it handles a user password change or a new password for a samba user. The Samba Active Directory Domain Controller can be configured to use a custom script to check for password complexity. This configuration can fail to verify password complexity when non-ASCII characters are used in the password, which could lead to weak passwords being set for samba users, making it vulnerable to dictionary attacks. | |||||
| CVE-2019-14861 | 4 Canonical, Fedoraproject, Opensuse and 1 more | 4 Ubuntu Linux, Fedora, Leap and 1 more | 2021-05-29 | 3.5 LOW | 5.3 MEDIUM |
| All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the (poorly named) dnsserver RPC pipe provides administrative facilities to modify DNS records and zones. Samba, when acting as an AD DC, stores DNS records in LDAP. In AD, the default permissions on the DNS partition allow creation of new records by authenticated users. This is used for example to allow machines to self-register in DNS. If a DNS record was created that case-insensitively matched the name of the zone, the ldb_qsort() and dns_name_compare() routines could be confused into reading memory prior to the list of DNS entries when responding to DnssrvEnumRecords() or DnssrvEnumRecords2() and so following invalid memory as a pointer. | |||||
| CVE-2020-25678 | 2 Fedoraproject, Redhat | 3 Fedora, Ceph, Ceph Storage | 2021-05-28 | 2.1 LOW | 4.4 MEDIUM |
| A flaw was found in ceph in versions prior to 16.y.z where ceph stores mgr module passwords in clear text. This can be found by searching the mgr logs for grafana and dashboard, with passwords visible. | |||||
| CVE-2021-21419 | 2 Eventlet, Fedoraproject | 2 Eventlet, Fedora | 2021-05-27 | 5.0 MEDIUM | 5.3 MEDIUM |
| Eventlet is a concurrent networking library for Python. A websocket peer may exhaust memory on Eventlet side by sending very large websocket frames. Malicious peer may exhaust memory on Eventlet side by sending highly compressed data frame. A patch in version 0.31.0 restricts websocket frame to reasonable limits. As a workaround, restricting memory usage via OS limits would help against overall machine exhaustion, but there is no workaround to protect Eventlet process. | |||||

| CVE-2021-23351 | 2 Fedoraproject, Go-proxyproto Project | 2 Fedora, Go-proxyproto | 2021-03-23 | 4.0 MEDIUM | 4.9 MEDIUM |
| The package github.com/pires/go-proxyproto before 0.5.0 are vulnerable to Denial of Service (DoS) via the parseVersion1() function. The reader in this package is a default bufio.Reader wrapping a net.Conn. It will read from the connection until it finds a newline. Since no limits are implemented in the code, a deliberately malformed V1 header could be used to exhaust memory in a server process using this code - and create a DoS. This can be exploited by sending a stream starting with PROXY and continuing to send data (which does not contain a newline) until the target stops acknowledging. The risk here is small, because only trusted sources should be allowed to send proxy protocol headers. | |||||
