setup before version 2.11.4-1.fc28 in Fedora and Red Hat Enterprise Linux added /sbin/nologin and /usr/sbin/nologin to /etc/shells. This violates security assumptions made by pam_shells and some daemons which allow access based on a user's shell being listed in /etc/shells. Under some circumstances, users which had their shell changed to /sbin/nologin could still access the system.

procps-ng before version 3.3.15 is vulnerable to a stack buffer overflow in pgrep. This vulnerability is mitigated by FORTIFY, as it involves strncat() to a stack-allocated string. When pgrep is compiled with FORTIFY (as on Red Hat Enterprise Linux and Fedora), the impact is limited to a crash.

DHCP packages in Red Hat Enterprise Linux 6 and 7, Fedora 28, and earlier are vulnerable to a command injection flaw in the NetworkManager integration script included in the DHCP client. A malicious DHCP server, or an attacker on the local network able to spoof DHCP responses, could use this flaw to execute arbitrary commands with root privileges on systems using NetworkManager and configured to obtain network configuration using the DHCP protocol.

The fedora-business-cards package before 1-0.1.beta1.fc17 on Fedora 17 and before 1-0.1.beta1.fc18 on Fedora 18 allows local users to cause a denial of service or write to arbitrary files via a symlink attack on /tmp/fedora-business-cards-buffer.svg.

fedora-cloud-atomic.ks in spin-kickstarts allows remote attackers to conduct man-in-the-middle attacks by leveraging use of HTTP to download Fedora Atomic updates.

Downstream version 1.0.46-1 of pure-ftpd as shipped in Fedora was vulnerable to packaging error due to which the original configuration was ignored after update and service started running with default configuration. This has security implications because of overriding security-related configuration. This issue doesn't affect upstream version of pure-ftpd.

The mod_nss module before 1.0.11 in Fedora allows remote attackers to obtain cipher lists due to incorrect parsing of multi-keyword cipherstring.

fedora-arm-installer up to and including 1.99.16 is vulnerable to local privilege escalation due to lack of checking the error condition of mount operation failure on unsafely created temporary directories.

The Fedora Nagios package uses "nagiosadmin" as the default password for the "nagiosadmin" administrator account, which makes it easier for remote attackers to obtain access by leveraging knowledge of the credentials.

The Tomcat package on Red Hat Enterprise Linux (RHEL) 7, Fedora, CentOS, Oracle Linux, and possibly other Linux distributions uses weak permissions for /usr/lib/tmpfiles.d/tomcat.conf, which allows local users to gain root privileges by leveraging membership in the tomcat group.

slapd/connection.c in 389 Directory Server (formerly Fedora Directory Server) 1.3.4.x before 1.3.4.7 allows remote attackers to cause a denial of service (infinite loop and connection blocking) by leveraging an abnormally closed connection.

389 Directory Server (formerly Fedora Directory Server) before 1.3.3.12 does not enforce the nsSSL3Ciphers preference when creating an sslSocket, which allows remote attackers to have unspecified impact by requesting to use a disabled cipher.

The OpenSSH server, as used in Fedora and Red Hat Enterprise Linux 7 and when running in a Kerberos environment, allows remote authenticated users to log in as another user when they are listed in the .k5users file of that user, which might bypass intended authentication requirements that would force a local login.

fedup 0.9.0 in Fedora 19, 20, and 21 uses a temporary directory with a static name for its download cache, which allows local users to cause a denial of service (prevention of system updates).

Untrusted search path vulnerability in Catfish 0.6.0 through 1.0.0, when a Fedora package such as 0.8.2-1 is not used, allows local users to gain privileges via a Trojan horse bin/catfish.pyc under the current working directory.

keystone/middleware/auth_token.py in OpenStack Nova Folsom, Grizzly, and Havana uses an insecure temporary directory for storing signing certificates, which allows local users to spoof servers by pre-creating this directory, which is reused by Nova, as demonstrated using /tmp/keystone-signing-nova on Fedora.
