CVSS v3.1 |
| An integer underflow vulnerability exists in the `nextstate()` function in `gpsd/packet.c` of gpsd versions prior to commit `ffa1d6f40bca0b035fc7f5e563160ebb67199da7`. When parsing a NAVCOM packet, the payload length is calculated using `lexer->length = (size_t)c - 4` without checking if the input byte `c` is less than 4. This results in an unsigned integer underflow, setting `lexer->length` to a very large value (near `SIZE_MAX`). The parser then enters a loop attempting to consume this massive number of bytes, causing 100% CPU utilization and a Denial of Service (DoS) condition. |
| iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. Prior to version 2.3.1.2, iccDEV is vulnerable to heap buffer overflow in the ToneMap parser. This issue has been patched in version 2.3.1.2. |
| The HTTPS server on Tapo C200 V3 does not properly validate the Content-Length header, which can lead to an integer overflow. An unauthenticated attacker on the same local network segment can send crafted HTTPS requests to trigger excessive memory allocation, causing the device to crash and resulting in denial-of-service (DoS). |
| In dpe, there is a possible memory corruption due to an integer overflow. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is needed for exploitation. Patch ID: ALPS10199779; Issue ID: MSV-4504. |
| In dpe, there is a possible out of bounds write due to an integer overflow. 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. Patch ID: ALPS10114841; Issue ID: MSV-4451. |
| An integer underflow vulnerability in the Silicon Labs Z-Wave Protocol Controller can lead to out of bounds memory reads. |
| A flaw was found in the SFTP server message decoding logic of libssh. The issue occurs due to an incorrect packet length check that allows an integer overflow when handling large payload sizes on 32-bit systems. This issue leads to failed memory allocation and causes the server process to crash, resulting in a denial of service. |
| A flaw exists in the nbdkit "blocksize" filter that can be triggered by a specific type of client request. When a client requests block status information for a very large data range, exceeding a certain limit, it causes an internal error in the nbdkit, leading to a denial of service. |
| There's a flaw in the nbdkit server when handling responses from its plugins regarding the status of data blocks. If a client makes a specific request for a very large data range, and a plugin responds with an even larger single block, the nbdkit server can encounter a critical internal error, leading to a denial-of-service. |
| A vulnerability has been identified in the libarchive library. This flaw involves an 'off-by-one' miscalculation when handling prefixes and suffixes for file names. This can lead to a 1-byte write overflow. While seemingly small, such an overflow can corrupt adjacent memory, leading to unpredictable program behavior, crashes, or in specific circumstances, could be leveraged as a building block for more sophisticated exploitation. This bug affects libarchive versions prior to 3.8.0. |
| A vulnerability has been identified in the libarchive library. This flaw involves an integer overflow that can be triggered when processing a Web Archive (WARC) file that claims to have more than INT64_MAX - 4 content bytes. An attacker could craft a malicious WARC archive to induce this overflow, potentially leading to unpredictable program behavior, memory corruption, or a denial-of-service condition within applications that process such archives using libarchive. This bug affects libarchive versions prior to 3.8.0. |
| FontForge GUtils XBM File Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of FontForge. 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 pixels within XBM files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-27865. |
| ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-12, in the WriteSVGImage function, using an int variable to store number_attributes caused an integer overflow. This, in turn, triggered a buffer overflow and caused a DoS attack. Version 7.1.2-12 fixes the issue. |
| An integer overflow in the RTPS protocol implementation of OpenDDS DDS before v3.33.0 allows attackers to cause a Denial of Service (DoS) via a crafted message. |
| An integer overflow in eProsima Fast-DDS v3.3 allows attackers to cause a Denial of Service (DoS) via a crafted input. |
| In GetTachyonCommand of tachyon_server_common.h, there is a possible out of bounds write due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. |
| An integer overflow vulnerability exists in the write method of the Buffer class in Robocode version 1.9.3.6. The method fails to properly validate the length of data being written, allowing attackers to cause an overflow, potentially leading to buffer overflows and arbitrary code execution. This vulnerability can be exploited by submitting specially crafted inputs that manipulate the data length, leading to potential unauthorized code execution. |
| A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to memory corruption or a crash. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: don't return unset power in ieee80211_get_tx_power()
We can get a UBSAN warning if ieee80211_get_tx_power() returns the
INT_MIN value mac80211 internally uses for "unset power level".
UBSAN: signed-integer-overflow in net/wireless/nl80211.c:3816:5

that no data is available. |
| In the Linux kernel, the following vulnerability has been resolved:
virtio-net: fix overflow inside virtnet_rq_alloc
When the frag just got a page, then may lead to regression on VM.
Specially if the sysctl net.core.high_order_alloc_disable value is 1,
then the frag always get a page when do refill.
Which could see reliable crashes or scp failure (scp a file 100M in size
to VM).
The issue is that the virtnet_rq_dma takes up 16 bytes at the beginning
of a new frag. When the frag size is larger than PAGE_SIZE,
everything is fine. However, if the frag is only one page and the
total size of the buffer and virtnet_rq_dma is larger than one page, an
overflow may occur.
The commit f9dac92ba908 ("virtio_ring: enable premapped mode whatever
use_dma_api") introduced this problem. And we reverted some commits to
fix this in last linux version. Now we try to enable it and fix this
bug directly.
Here, when the frag size is not enough, we reduce the buffer len to fix
this problem. |
