CVSS v3.1 |
| LibTIFF 4.4.0 has an out-of-bounds write in _TIFFmemcpy in libtiff/tif_unix.c:346 when called from extractImageSection, tools/tiffcrop.c:6860, allowing attackers to cause a denial-of-service via a crafted tiff file. For users that compile libtiff from sources, the fix is available with commit 236b7191. |
| Multiple command injections and stack-based buffer overflows vulnerabilities in the SubNet_handler_func function of spx_restservice allow an attacker to execute arbitrary code with the same privileges as the server user (root). This issue affects: Lanner Inc IAC-AST2500A standard firmware version 1.10.0. |
| drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-space client to corrupt the monitor's internal memory. |
| Nginx NJS v0.7.4 was discovered to contain a segmentation violation in njs_promise_reaction_job. NOTE: the vendor disputes the significance of this report because NJS does not operate on untrusted input. |
| D-Link DIR-816 A2 1.10 B05 was discovered to contain a stack overflow via the pskValue parameter in the setRepeaterSecurity function. |
| D-Link DIR-816 A2 1.10 B05 was discovered to contain a stack overflow via the wizardstep54_pskpwd parameter at /goform/form2WizardStep54. |
| D-Link DIR-816 A2 1.10 B05 was discovered to contain a stack overflow via the pskValue parameter in the setSecurity function. |
| D-Link DIR-816 A2 1.10 B05 was discovered to contain a stack overflow via the wizardstep4_pskpwd parameter at /goform/form2WizardStep4. |
| D-Link DIR-816 A2 1.10 B05 was discovered to contain a stack overflow via the srcip parameter at /goform/form2IPQoSTcAdd. |
| A vulnerability in fab_seg.c.h libraries of all Brocade Fabric OS versions before Brocade Fabric OS v9.1.1, v9.0.1e, v8.2.3c, v8.2.0_cbn5, 7.4.2j could allow local authenticated attackers to exploit stack-based buffer overflows and execute arbitrary code as the root user account. |
| A vulnerability in Brocade Fabric OS CLI before Brocade Fabric OS v9.1.0, 9.0.1e, 8.2.3c, 8.2.0cbn5, 7.4.2.j could allow a remote authenticated attacker to perform stack buffer overflow using in “firmwaredownload” and “diagshow” commands. |
| Finit provides fast init for Linux systems. Finit's urandom plugin has a heap buffer overwrite vulnerability at boot which leads to it overwriting other parts of the heap, possibly causing random instabilities and undefined behavior. The urandom plugin is enabled by default, so this bug affects everyone using Finit 4.2 or later that do not explicitly disable the plugin at build time. This bug is fixed in Finit 4.12. Those who cannot upgrade or backport the fix to urandom.c are strongly recommended to disable the plugin in the call to the `configure` script. |

| In the Linux kernel, the following vulnerability has been resolved:
arm64: entry: avoid kprobe recursion
The cortex_a76_erratum_1463225_debug_handler() function is called when
handling debug exceptions (and synchronous exceptions from BRK
instructions), and so is called when a probed function executes. If the
compiler does not inline cortex_a76_erratum_1463225_debug_handler(), it
can be probed.
If cortex_a76_erratum_1463225_debug_handler() is probed, any debug
exception or software breakpoint exception will result in recursive
exceptions leading to a stack overflow. This can be triggered with the
ftrace multiple_probes selftest, and as per the example splat below.
This is a regression caused by commit:
6459b8469753e9fe ("arm64: entry: consolidate Cortex-A76 erratum 1463225 workaround")
... which removed the NOKPROBE_SYMBOL() annotation associated with the
function.
My intent was that cortex_a76_erratum_1463225_debug_handler() would be
inlined into its caller, el1_dbg(), which is marked noinstr and cannot
be probed. Mark cortex_a76_erratum_1463225_debug_handler() as
__always_inline to ensure this.
Example splat prior to this patch (with recursive entries elided):
| # echo p cortex_a76_erratum_1463225_debug_handler > /sys/kernel/debug/tracing/kprobe_events
| # echo p do_el0_svc >> /sys/kernel/debug/tracing/kprobe_events
| # echo 1 > /sys/kernel/debug/tracing/events/kprobes/enable
| Insufficient stack space to handle exception!

| An issue was discovered in QEMU 7.1.0 through 8.2.1. register_vfs in hw/pci/pcie_sriov.c does not set NumVFs to PCI_SRIOV_TOTAL_VF, and thus interaction with hw/nvme/ctrl.c is mishandled. |
