CVSS v3.1 |
| SpotDialup 1.6.7 contains a denial of service vulnerability in the registration key input field that allows attackers to crash the application. Attackers can generate a 1000-character buffer payload and paste it into the 'Key' field to trigger an application crash. |
| ShareAlarmPro contains a denial of service vulnerability that allows attackers to crash the application by supplying an oversized registration key. Attackers can generate a 1000-character buffer payload to trigger an application crash when pasted into the registration key field. |
| Dnss Domain Name Search Software contains a denial of service vulnerability that allows attackers to crash the application by overflowing the 'Name' input field. Attackers can generate a 1000-character buffer payload and paste it into the registration name field to trigger an application crash. |

wifi: brcmfmac: Fix potential shift-out-of-bounds in brcmf_fw_alloc_request()
This patch fixes a shift-out-of-bounds in brcmfmac that occurs in
BIT(chiprev) when a 'chiprev' provided by the device is too large.
It should also not be equal to or greater than BITS_PER_TYPE(u32)
as we do bitwise AND with a u32 variable and BIT(chiprev). The patch
adds a check that makes the function return NULL if that is the case.
Note that the NULL case is later handled by the bus-specific caller,
brcmf_usb_probe_cb() or brcmf_usb_reset_resume(), for example.
Found by a modified version of syzkaller.

Through the vmcore, I found it's because in tracing_read_pipe(),
ring_buffer_empty_cpu() found some buffer is not empty but then it
cannot read anything due to "rb_num_of_entries() == 0" always true,
Then it infinitely loop the procedure due to user buffer not been
filled, see following code path:
tracing_read_pipe() {
... ...
waitagain:
tracing_wait_pipe() // 1. find non-empty buffer here
trace_find_next_entry_inc() // 2. loop here try to find an entry
__find_next_entry()
ring_buffer_empty_cpu(); // 3. find non-empty buffer
peek_next_entry() // 4. but peek always return NULL
ring_buffer_peek()
rb_buffer_peek()
rb_get_reader_page()
// 5. because rb_num_of_entries() == 0 always true here
// then return NULL
// 6. user buffer not been filled so goto 'waitgain'
// and eventually leads to an deadloop in kernel!!!
}
By some analyzing, I found that when resetting ringbuffer, the 'entries'
of its pages are not all cleared (see rb_reset_cpu()). Then when reducing
the ringbuffer, and if some reduced pages exist dirty 'entries' data, they
will be added into 'cpu_buffer->overrun' (see rb_remove_pages()), which
cause wrong 'overrun' count and eventually cause the deadloop issue.
To fix it, we need to clear every pages in rb_reset_cpu(). |
| A heap buffer overflow in the processRequest function of Open TFTP Server MultiThreaded v1.7 allows attackers to cause a Denial of Service (DoS) via a crafted DATA packet. |
| User-controlled chunkSize metadata from MongoDB lacks appropriate validation allowing malformed GridFS metadata to overflow the bounding container. |
| In update_freq_data of , there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. |
| WMV to AVI MPEG DVD WMV Convertor 4.6.1217 contains a buffer overflow vulnerability that allows attackers to crash the application by providing an oversized license input. Attackers can generate a 6000-byte payload and paste it into the 'License Name and License Code' field to trigger an application crash. |
| ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-15, a stack-based buffer overflow exists in the ImageMagick FTXT image reader. A crafted FTXT file can cause out-of-bounds writes on the stack, leading to a crash. Version 7.1.2-15 contains a patch. |
| ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a stack buffer overflow occurs when processing the an attribute in msl.c. A long value overflows a fixed-size stack buffer, leading to memory corruption. Versions 7.1.2-15 and 6.9.13-40 contain a patch. |
| A post-authentication Out-of-bounds Read vulnerability in SonicOS allows a remote attacker to crash a firewall. |
| GIMP PSP File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of PSP files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28232. |
| Multiple post-authentication stack-based buffer overflow vulnerabilities in the SonicOS management interface due to improper bounds checking in a API endpoint. |
| In wlan AP driver, there is a possible out of bounds write due to an incorrect bounds check. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation.

| Meshtastic is an open source mesh networking solution. The Meshtastic firmware (starting from version 2.5) introduces asymmetric encryption (PKI) for direct messages, but when the `pki_encrypted` flag is missing, the firmware silently falls back to legacy AES-256-CTR channel encryption. This was an intentional decision to maintain backwards compatibility. However, the end-user applications, like Web app, iOS/Android app, and applications built on top of Meshtastic using the SDK, did not have a way to differentiate between end-to-end encrypted DMs and the legacy DMs. This creates a downgrade attack path where adversaries who know a shared channel key can craft and inject spoofed direct messages that are displayed as if they were PKC encrypted. Users are not given any feedback of whether a direct message was decrypted with PKI or with legacy symmetric encryption, undermining the expected security guarantees of the PKI rollout. Version 2.7.15 fixes this issue. |
