Rukovoditel version 3.3.1 suffers from a CSV injection vulnerability.

The threat actors behind BlackCat ransomware have come up with an improved variant that prioritizes speed and stealth in an attempt to bypass security guardrails and achieve their goals. The new version, dubbed Sphynx and announced in February 2023, packs a "number of updated capabilities that strengthen the group's efforts to evade detection," IBM Security X-Force said in a new analysis.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a recently patched critical security flaw in Zyxel gear to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. Tracked as CVE-2023-28771 (CVSS score: 9.8), the issue relates to a command injection flaw impacting different firewall models that could enable an unauthenticated attacker

A flaw was found in the fixed buffer registration code for io_uring (io_sqe_buffer_register in io_uring/rsrc.c) in the Linux kernel that allows out-of-bounds access to physical memory beyond the end of the buffer. This flaw enables full local privilege escalation.

A use after free flaw was found in hfsplus_put_super in fs/hfsplus/super.c in the Linux Kernel. This flaw could allow a local user to cause a denial of service problem.

** DISPUTED ** An issue was discovered in BMC Patrol through 23.1.00. The agent's configuration can be remotely modified (and, by default, authentication is not required). Some configuration fields related to SNMP (e.g., masterAgentName or masterAgentStartLine) result in code execution when the agent is restarted. NOTE: the vendor's perspective is "These are not vulnerabilities for us as we have provided the option to implement the authentication."

An issue was discovered in the Linux kernel through 6.3.5. There is a use-after-free in xfs_btree_lookup_get_block in fs/xfs/libxfs/xfs_btree.c because fs/xfs/xfs_buf_item_recover.c does not perform buffer content verification when log replay is skipped.
