moodle before versions 3.5.2, 3.4.5, 3.3.8 is vulnerable to a boost theme - blog search GET parameter insufficiently filtered. The breadcrumb navigation provided by Boost theme when displaying search results of a blog were insufficiently filtered, which could result in reflected XSS if a user followed a malicious link containing JavaScript in the search parameter.

moodle before versions 3.5.2, 3.4.5, 3.3.8, 3.1.14 is vulnerable to an XML import of ddwtos could lead to intentional remote code execution. When importing legacy 'drag and drop into text' (ddwtos) type quiz questions, it was possible to inject and execute PHP code from within the imported questions, either intentionally or by importing questions from an untrusted source.

samba: Unprivileged adding of CNAME record causing loop in AD LDAP server

A denial of service vulnerability was discovered in Samba's LDAP server before versions 4.7.12, 4.8.7, and 4.9.3. A CNAME loop could lead to infinite recursion in the server. An unprivileged local attacker could create such an entry, leading to denial of service.

JBoss/WildFly: iiop does not honour strict transport confidentiality

The IIOP OpenJDK Subsystem in WildFly before version 14.0.0 does not honour configuration when SSL transport is required. Servers before this version that are configured with the following setting allow clients to create plaintext connections: <transport-config confidentiality="required" trust-in-target="supported"/>

PowerDNS Authoritative Server 4.1.0 up to 4.1.4 inclusive and PowerDNS Recursor 4.0.0 up to 4.1.4 inclusive are vulnerable to a packet cache pollution via crafted query that can lead to denial of service.

kernel: use-after-free Read in vhost_transport_send_pkt

A flaw was found in the Linux Kernel where an attacker may be able to have an uncontrolled read to kernel-memory from within a vm guest. A race condition between connect() and close() function may allow an attacker using the AF_VSOCK protocol to gather a 4 byte information leak or possibly intercept or corrupt AF_VSOCK messages destined to other clients.

389-ds-base: Server crash through modify command with large DN

A vulnerability was discovered in 389-ds-base through versions 1.3.7.10, 1.3.8.8 and 1.4.0.16. The lock controlling the error log was not correctly used when re-opening the log file in log__error_emergency(). An attacker could send a flood of modifications to a very large DN, which would cause slapd to crash.

katello: SQL inject in errata-related REST API

A SQL injection flaw was found in katello's errata-related API. An authenticated remote attacker can craft input data to force a malformed SQL query to the backend database, which will leak internal IDs. This is issue is related to an incomplete fix for CVE-2016-3072. Version 3.10 and older is vulnerable.

libtirpc: Segmentation fault in makefd_xprt return value in svc_vc.c

A null-pointer dereference vulnerability was found in libtirpc before version 0.3.3-rc3. The return value of makefd_xprt() was not checked in all instances, which could lead to a crash when the server exhausted the maximum number of available file descriptors. A remote attacker could cause an rpc-based application to crash by flooding it with new connections.

libtirpc: Infinite loop in EMFILE case in svc_vc.c

An infinite loop vulnerability was found in libtirpc before version 1.0.2-rc2. With the port to using poll rather than select, exhaustion of file descriptors would cause the server to enter an infinite loop, consuming a large amount of CPU time and denying service to other clients until restarted.

openstack-rabbitmq-container: Insecure download of rabbitmq_clusterer during docker build

The OpenStack RabbitMQ container image insecurely retrieves the rabbitmq_clusterer component over HTTP during the build stage. This could potentially allow an attacker to serve malicious code to the image builder and install in the resultant container image. Version of openstack-rabbitmq-container and openstack-containers as shipped with Red Hat Openstack 12, 13, 14 are believed to be vulnerable.

kernel: crash (possible privesc) in kernel crypto api.

A flaw was found in the crypto subsystem of the Linux kernel before version kernel-4.15-rc4. The "null skcipher" was being dropped when each af_alg_ctx was freed instead of when the aead_tfm was freed. This can cause the null skcipher to be freed while it is still in use leading to a local user being able to crash the system or possibly escalate privileges.

kernel: NULL pointer dereference in fs/hfsplus/dir.c:hfsplus_lookup() when operating on a file in a crafted hfs+ image

An issue was discovered in the Linux kernel through 4.17.10. There is a NULL pointer dereference and panic in hfsplus_lookup() in fs/hfsplus/dir.c when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory.

kernel: NULL pointer dereference in fs/crypto/crypto.c:fscrypt_do_page_crypto() when operating on a corrupted f2fs image

An issue was discovered in the Linux kernel through 4.17.10. There is a NULL pointer dereference in fscrypt_do_page_crypto() in fs/crypto/crypto.c when operating on a file in a corrupted f2fs image.

kernel: Buffer overflow in fs/f2fs/inline.c:truncate_inline_inode() when unmounting a crafted f2fs image

An issue was discovered in the Linux kernel through 4.17.10. There is a buffer overflow in truncate_inline_inode() in fs/f2fs/inline.c when umounting an f2fs image, because a length value may be negative.

kernel: Out-of-bounds access in fs/f2fs/segment.c:__remove_dirty_segment() when mounting a crafted f2fs image

An issue was discovered in the Linux kernel through 4.17.10. There is an out-of-bounds access in __remove_dirty_segment() in fs/f2fs/segment.c when mounting an f2fs image.

kernel: Invalid pointer dereference in io_ctl_map_page() when mounting and operating a crafted btrfs image

An issue was discovered in the Linux kernel through 4.17.10. There is an invalid pointer dereference in io_ctl_map_page() when mounting and operating a crafted btrfs image, because of a lack of block group item validation in check_leaf_item in fs/btrfs/tree-checker.c.

kernel: Invalid pointer dereference in btrfs_root_node() when mounting a crafted btrfs image

An issue was discovered in the Linux kernel through 4.17.10. There is an invalid pointer dereference in btrfs_root_node() when mounting a crafted btrfs image, because of a lack of chunk block group mapping validation in btrfs_read_block_groups in fs/btrfs/extent-tree.c, and a lack of empty-tree checks in check_leaf in fs/btrfs/tree-checker.c.

kernel: Use-after-free in try_merge_free_space() when mounting crafted btrfs image

An issue was discovered in the Linux kernel through 4.17.10. There is a use-after-free in try_merge_free_space() when mounting a crafted btrfs image, because of a lack of chunk type flag checks in btrfs_check_chunk_valid in fs/btrfs/volumes.c.

kernel: Out-of-bounds access in write_extent_buffer() when mounting and operating a crafted btrfs image

An issue was discovered in the Linux kernel through 4.17.10. There is out-of-bounds access in write_extent_buffer() when mounting and operating a crafted btrfs image, because of a lack of verification that each block group has a corresponding chunk at mount time, within btrfs_read_block_groups in fs/btrfs/extent-tree.c.
