In Wireshark 2.4.0 to 2.4.12 and 2.6.0 to 2.6.6, the ASN.1 BER and related dissectors could crash. This was addressed in epan/dissectors/packet-ber.c by preventing a buffer overflow associated with excessive digits in time values.

A flaw was found in the way samba implemented an RPC endpoint emulating the Windows registry service API. An unprivileged attacker could use this flaw to create a new registry hive file anywhere they have unix permissions which could lead to creation of a new file in the Samba share. Versions before 4.8.11, 4.9.6 and 4.10.2 are vulnerable.

A flaw was found in libvirtd. A null pointer in virJSONValueObjectHasKey function in util/virjson.c triggers a crash, resulting in remote denial of service via guest agent.

A vulnerability was found in sssd where, if a user was configured with no home directory set, sssd would return '/' (the root directory) instead of '' (the empty string / no home directory). This could impact services that restrict the user's filesystem access to within their home directory through chroot().

Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Networking). Supported versions that are affected are Java SE: 7u201, 8u192 and 11.0.1; Java SE Embedded: 8u191. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.0 Base Score 3.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N).

An issue was discovered in fs/f2fs/inline.c in the Linux kernel through 4.4. A denial of service (out-of-bounds memory access and BUG) can occur for a modified f2fs filesystem image in which an inline inode contains an invalid reserved blkaddr.

Cross-site scripting (XSS) vulnerability in the link dialogue in GUI editor in MoinMoin before 1.9.10 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

A new exploitation technique called key reinstallation attacks used to break Wi-Fi handshakes that negotiate session keys was discovered. These attacks target the Wi-Fi/WPA2 standard. An adversary can trick a client or Access Point (AP) into reinstalling an already-in use group key in 4-way handshake. While reinstalling the already in-use key, the associated packet number (sometimes also called nonce) and receive replay counter is reset. This causes nonce reuse, voiding any security the underlying encryption protocol is supposed to provide. For example, it allows decryption or injection of frames, and enables an attacker to replay frames.

Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11w allows reinstallation of the Integrity Group Temporal Key (IGTK) during the group key handshake, allowing an attacker within radio range to spoof frames from access points to clients.

Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Tunneled Direct-Link Setup (TDLS) Peer Key (TPK) during the TDLS handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames.

Wi-Fi Protected Access (WPA and WPA2) that support 802.11v allows reinstallation of the Group Temporal Key (GTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame, allowing an attacker within radio range to replay frames from access points to clients.

Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11w allows reinstallation of the Integrity Group Temporal Key (IGTK) during the four-way handshake, allowing an attacker within radio range to spoof frames from access points to clients.

A vulnerability exists in libgwenhywfar through 4.12.0 due to the usage of outdated bundled CA certificates.

Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Station-To-Station-Link (STSL) Transient Key (STK) during the PeerKey handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames.
