infinispan-server-rest: Actions with effects should not be permitted via GET requests using REST API

A flaw was found in Infinispan version 10, where it is possible to perform various actions that could have side effects using GET requests. This flaw allows an attacker to perform a cross-site request forgery (CSRF) attack.

kernel: kernel: DAX hugepages not considered during mremap

A flaw was found in the Linux Kernel in versions after 4.5-rc1 in the way mremap handled DAX Huge Pages. This flaw allows a local attacker with access to a DAX enabled storage to escalate their privileges on the system.

kernel: uninitialized kernel data leak in userspace coredumps

A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an attacker with a local account to crash a trivial program and exfiltrate private kernel data.

undertow: invalid HTTP request with large chunk size

A flaw was found in Undertow in versions before 2.1.1.Final, regarding the processing of invalid HTTP requests with large chunk sizes. This flaw allows an attacker to take advantage of HTTP request smuggling.

wildfly-elytron: session fixation when using FORM authentication

A flaw was found in WildFly Elytron version 1.11.3.Final and before. When using WildFly Elytron FORM authentication with a session ID in the URL, an attacker could perform a session fixation attack. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

undertow: Memory exhaustion issue in HttpReadListener via "Expect: 100-continue" header

A flaw was discovered in Undertow in versions before Undertow 2.1.1.Final where certain requests to the "Expect: 100-continue" header may cause an out of memory error. This flaw may potentially lead to a denial of service.

kernel: use-after-free in cdev_put() when a PTP device is removed while it's chardev is open

There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed, it can cause an exploitable condition as the process wakes up to terminate and clean all attached files. The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the inode.

Improper input validation in BIOS firmware for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege via local access.

kubernetes: Incorrect rule injection in CNI portmap plugin

Cloud Native Computing Foundation (CNCF) CNI (Container Networking Interface) 0.7.4 has a network firewall misconfiguration which affects Kubernetes. The CNI 'portmap' plugin, used to setup HostPorts for CNI, inserts rules at the front of the iptables nat chains; which take precedence over the KUBE- SERVICES chain. Because of this, the HostPort/portmap rule could match incoming traffic even if there were better fitting, more specific service definition rules like NodePorts later in the chain. The issue is fixed in CNI 0.7.5 and Kubernetes 1.11.9, 1.12.7, 1.13.5, and 1.14.0.

bash: BASH_CMD is writable in restricted bash shells

rbash in Bash before 4.4-beta2 did not prevent the shell user from modifying BASH_CMDS, thus allowing the user to execute any command with the permissions of the shell.

Potential recycling of random numbers used in cryptography exists within PuTTY before 0.71.

Multiple denial-of-service attacks that can be triggered by writing to the terminal exist in PuTTY versions before 0.71.

A remotely triggerable memory overwrite in RSA key exchange in PuTTY before 0.71 can occur before host key verification.

php: Uninitialized read in exif_process_IFD_in_TIFF

An issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an uninitialized read in exif_process_IFD_in_TIFF.

php: Invalid read in exif_process_SOFn()

An issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an Invalid Read in exif_process_SOFn.

php: Uninitialized read in exif_process_IFD_in_MAKERNOTE

An issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an uninitialized read in exif_process_IFD_in_MAKERNOTE because of mishandling the data_len variable.

php: Uninitialized read in exif_process_IFD_in_MAKERNOTE

An issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an uninitialized read in exif_process_IFD_in_MAKERNOTE because of mishandling the maker_note->offset relationship to value_len.

php: File rename across filesystems may allow unwanted access during processing

An issue was discovered in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. Due to the way rename() across filesystems is implemented, it is possible that file being renamed is briefly available with wrong permissions while the rename is ongoing, thus enabling unauthorized users to access the data.

kernel: out-of-bounds read/write in et/ipv4/netfilter/nf_nat_snmp_basic_main.c in the SNMP NAT module

In the Linux kernel before 4.20.12, net/ipv4/netfilter/nf_nat_snmp_basic_main.c in the SNMP NAT module has insufficient ASN.1 length checks (aka an array index error), making out-of-bounds read and write operations possible, leading to an OOPS or local privilege escalation. This affects snmp_version and snmp_helper.

binutils: heap-based buffer overflow in function process_mips_specific in readelf.c

An issue was discovered in GNU Binutils 2.32. It is a heap-based buffer overflow in process_mips_specific in readelf.c via a malformed MIPS option section.
