rubygem-sprockets before versions 2.12.5, 3.7.2 and 4.0.0beta8 are vulnerable to a path traversal flaw in the sprockets/server.rb:forbiddenrequest?() function. A remote attacker could exploit this to read arbitrary files from the Sprockets server.

openjpeg: A heap-based buffer overflow flaw was found in the patch for CVE-2013-6045. A crafted j2k image could cause the application to crash, or potentially execute arbitrary code.
An issue was discovered in HAProxy before 1.8.8. The incoming H2 frame length was checked against the maxframesize setting instead of being checked against the bufsize. The maxframesize only applies to outgoing traffic and not to incoming, so if a large enough frame size is advertised in the SETTINGS frame, a wrapped frame will be defragmented into a temporary allocated buffer where the second fragment may overflow the heap by up to 16 kB. It is very unlikely that this can be exploited for code execution given that buffers are very short lived and their addresses not realistically predictable in production, but the likelihood of an immediate crash is absolutely certain.
A command injection flaw was found in the NetworkManager integration script included in the DHCP client packages in Red Hat Enterprise Linux. 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.
A security issue was found in pcs deamon that permits an authorized user (with write permission in pcsd) to escalate privileges and write to any file in the system using a malicious REST call.
A flaw was found in the "Leaf and Chain" OCSP policy implementation in JSS' CryptoManager versions after 4.4.6, 4.5.3, 4.6.0, where it implicitly trusted the root certificate of a certificate chain. Applications using this policy may not properly verify the chain and could be vulnerable to attacks such as Man in the Middle.
