drm/shmem-helper: Fix BUG_ON() on mmap(PROT_WRITE, MAP_PRIVATE)

In the Linux kernel, the following vulnerability has been resolved: drm/shmem-helper: Fix BUG_ON() on mmap(PROT_WRITE, MAP_PRIVATE) Lack of check for copy-on-write (COW) mapping in drm_gem_shmem_mmap allows users to call mmap with PROT_WRITE and MAP_PRIVATE flag causing a kernel panic due to BUG_ON in vmf_insert_pfn_prot: BUG_ON((vma->vm_flags & VM_PFNMAP) && is_cow_mapping(vma->vm_flags)); Return -EINVAL early if COW mapping is detected. This bug affects all drm drivers using default shmem helpers. It can be reproduced by this simple example: void *ptr = mmap(0, size, PROT_WRITE, MAP_PRIVATE, fd, mmap_offset); ptr[0] = 0;

PostgreSQL PL/Perl environment variable changes execute arbitrary code

Incorrect control of environment variables in PostgreSQL PL/Perl allows an unprivileged database user to change sensitive process environment variables (e.g. PATH). That often suffices to enable arbitrary code execution, even if the attacker lacks a database server operating system user. Versions before PostgreSQL 17.1, 16.5, 15.9, 14.14, 13.17, and 12.21 are affected.

IBM Security Access Manager Container XML external entity injection

IBM Security Access Manager Container (IBM Security Verify Access Appliance 10.0.0.0 through 10.0.6.1 and IBM Security Verify Access Docker 10.0.0.0 through 10.0.6.1) is vulnerable to an XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources. IBM X-Force ID: 254783.

netfilter: nft_socket: remove WARN_ON_ONCE on maximum cgroup level

In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_socket: remove WARN_ON_ONCE on maximum cgroup level cgroup maximum depth is INT_MAX by default, there is a cgroup toggle to restrict this maximum depth to a more reasonable value not to harm performance. Remove unnecessary WARN_ON_ONCE which is reachable from userspace.

A denial of service vulnerability exists in the Distributed Transaction Commit/Abort Operation functionality of Bloomberg Comdb2 8.1. A specially crafted network packet can lead to a denial of service. An attacker can send a malicious packet to trigger this vulnerability.

A denial of service vulnerability exists in the Bloomberg Comdb2 8.1 database when handling a distributed transaction heartbeat. A specially crafted protocol buffer message can lead to a denial of service. An attacker can simply connect to a database instance over TCP and send the crafted message to trigger this vulnerability.

nilfs2: handle errors that nilfs_prepare_chunk() may return

In the Linux kernel, the following vulnerability has been resolved: nilfs2: handle errors that nilfs_prepare_chunk() may return Patch series "nilfs2: fix issues with rename operations". This series fixes BUG_ON check failures reported by syzbot around rename operations, and a minor behavioral issue where the mtime of a child directory changes when it is renamed instead of moved. This patch (of 2): The directory manipulation routines nilfs_set_link() and nilfs_delete_entry() rewrite the directory entry in the folio/page previously read by nilfs_find_entry(), so error handling is omitted on the assumption that nilfs_prepare_chunk(), which prepares the buffer for rewriting, will always succeed for these. And if an error is returned, it triggers the legacy BUG_ON() checks in each routine. This assumption is wrong, as proven by syzbot: the buffer layer called by nilfs_prepare_chunk() may call nilfs_get_block() if necessary, which may fail due to metadata corruption or other reasons. This has been there all along, but improved sanity checks and error handling may have made it more reproducible in fuzzing tests. Fix this issue by adding missing error paths in nilfs_set_link(), nilfs_delete_entry(), and their caller nilfs_rename().

poppler: Reachable assertion in Object.h

An issue was discovered in Poppler 22.08.0. There is a reachable assertion in Object.h, will lead to denial of service because PDFDoc::replacePageDict in PDFDoc.cc lacks a stream check before saving an embedded file.

poppler: reachable assertion due to a failure in markObject()

A reachable Object::getString assertion in Poppler 22.07.0 allows attackers to cause a denial of service due to a failure in markObject.

poppler: abort in main() in pdfunite.cc

An issue was discovered in Poppler 22.07.0. There is a reachable abort which leads to denial of service because the main function in pdfunite.cc lacks a stream check before saving an embedded file.

DeadBolt Ransomware

An externally controlled reference to a resource vulnerability has been reported to affect QNAP NAS running Photo Station. If exploited, This could allow an attacker to modify system files. We have already fixed the vulnerability in the following versions: QTS 5.0.1: Photo Station 6.1.2 and later QTS 5.0.0/4.5.x: Photo Station 6.0.22 and later QTS 4.3.6: Photo Station 5.7.18 and later QTS 4.3.3: Photo Station 5.4.15 and later QTS 4.2.6: Photo Station 5.2.14 and later

An XML external entity or XXE vulnerability in the SAML component of Ivanti Connect Secure (9.x, 22.x), Ivanti Policy Secure (9.x, 22.x) and ZTA gateways which allows an attacker to access certain restricted resources without authentication.

Reachable Assertion vulnerability in Open5GS

Reachable Assertion vulnerability in Open5GS up to version 2.7.6 allows attackers with connectivity to the NRF to cause a denial of service. This is achieved by sending the creation of an NF with an invalid type via SBI and then requesting its data. The NRF executes a check that crashes the process, leaving the discovery service unresponsive.

Reachable Assertion vulnerability in Open5GS

Reachable Assertion vulnerability in Open5GS up to version 2.7.6 allows attackers with connectivity to the NRF to cause a denial of service. An SBI request that deletes the NRF's own registry causes a check that ends up crashing the NRF process and renders the discovery service unavailable.
