Busybox: busybox: romfs volume id parsing performs unbounded memcpy into fixed-size label buffer, causing heap overflow

BusyBox romfs volume ID parsing uses unbounded strlen on attacker-controlled metadata, causing a heap buffer overflow when processing crafted filesystem images.

x86/alternatives: Exclude text poking against change_page_attr()

In the Linux kernel, the following vulnerability has been resolved: x86/alternatives: Exclude text poking against change_page_attr() From time to time, the following BUG can be observed in the x86 alternatives patching code [0]: > kernel BUG at arch/x86/kernel/alternative.c:2576! > Oops: invalid opcode: 0000 [#1] SMP NOPTI > CPU: 0 UID: 0 PID: 355 Comm: (udev-worker) Not tainted 7.1.3-1-default #1 PREEMPT(full) openSUSE Tumbleweed 8c1795b03ec64f997e57a8ad38b1161e3b98da64 > Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS unknown 02/02/2022 > RIP: 0010:__text_poke+0x2aa/0x450 > Call Trace: > <TASK> > smp_text_poke_batch_finish+0x2a7/0x320 > __static_call_transform+0xb7/0x220 > arch_static_call_transform+0x5b/0xb0 > __static_call_init+0xe9/0x270 > static_call_module_notify+0x11f/0x150 > notifier_call_chain+0x61/0xe0 > blocking_notifier_call_chain_robust+0x63/0xc0 > load_module+0x1c92/0x20c0 > init_module_from_file+0xd8/0x140 > idempotent_init_module+0x100/0x2f0 > __x64_sys_finit_module+0x71/0xe0 > do_syscall_64+0xe1/0x610 > entry_SYSCALL_64_after_hwframe+0x76/0x7e which matches the following BUG_ON() in alternative.c: /* * If something went wrong, crash and burn since recovery paths are not * implemented. */ BUG_ON(!pages[0] || (cross_page_boundary && !pages[1])); This can happen if vmalloc_to_page() fails, for any reason. Such can happen if text poking races with CPA, which can possibly result in the collapsing of page tables (or breaking of PMD hugepages). It is not a problem for most users of vmalloc_to_page() (they solely own the vmalloc'd range) but, when CONFIG_ARCH_HAS_EXECMEM_ROX=y, various modules own a single execmem vmalloc range, and can call set_memory_*() in parallel on it. This can happen to race against __text_poke and cause havoc in vmalloc_to_page(). Fix it by excluding against CPA using the init_mm mmap read lock. [ dhansen: Fix up SoB ordering. The actual code flow here was: Pedro=>Lorenzo=>Mike=>Me which is reflected in the SoB chain now. I *believe* Mike simply picked up Lorenzo's update to Pedro's post from the Link ]

Microsoft Outlook and Word Remote Code Execution Vulnerability

Heap-based buffer overflow in Microsoft Office allows an unauthorized attacker to execute code locally.

Windows Storage Information Disclosure Vulnerability

Insertion of sensitive information into externally-accessible file or directory in Windows Storage allows an authorized attacker to disclose information locally.

Zoraxy 3.2.3 through 3.3.4 Client IP Spoofing via X-Forwarded-For IPv6

Zoraxy versions 3.2.3 through 3.3.4 fail to properly parse IPv6 addresses in the RemoteAddr field when setting forwarded headers. Unauthenticated attackers connecting over IPv6 can supply arbitrary X-Forwarded-For values to spoof their source IP and bypass authorization provider IP-based access controls.

OpenMetadata through 2.0.2 SSRF via Webhook URL Validation Bypass

OpenMetadata through 2.0.2 contains a server-side request forgery vulnerability in the URLValidator.validateURL function that fails to properly resolve DNS hostnames and validate internal addresses. Users permitted to create or update EventSubscription can set webhook destinations to internal hosts, allowing the server to send requests to private networks and cloud metadata endpoints while returning HTTP status codes that enable blind SSRF probing.
