CVSS v3.1 |
| diff3 tool from GNU diffutils is vulnerable to a heap‑based buffer overflow due to multiple signed integer overflows in line‑mapping calculations. Incorrect arithmetic in mapping line ranges can result in corrupted values being used for memory allocation and loop bounds.
When processing crafted diff output, these overflows may cause the application to allocate insufficient memory and subsequently perform out‑of‑bounds writes during internal processing.
An attacker who can control the output of the diff program used by diff3 (e.g. via --diff-program pointing to a malicious script) can trigger out-of-bounds writes, resulting in a crash and potentially remote code execution depending on the environment.
This issue has been fixed in commit 9ff04d5b84743e331e80b589335a52c5480d1815
NOTE:
The project maintainers claim that this is not a security issue. They state that the worst outcome this issue can cause is a crash of diff and that it cannot be used to escalate privileges. |
| Coturn is a free open source implementation of TURN and STUN Server. From 4.5.2 through 4.14.0, when Coturn is started with --acme-redirect <URL> and exposes a plaintext-TCP listener, an unauthenticated remote client can send a single ordinary HTTP GET request and receive a 301 response whose Location header contains up to ~870 bytes of adjacent process heap memory. The leaked region is a recycled network receive buffer that is reused without being zeroed, so on a busy server it can contain data from other clients' requests (TURN credentials, OAuth tokens, relayed payloads). Root cause is a signed→unsigned conversion. This issue is fixed in version 4.15.0. |

| Autel MaxiCharger AC Elite Home WebSockets Integer Underflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Autel MaxiCharger AC Elite Home EV chargers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of WebSocket messages related to the OCPP service. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-29113. |

| ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to both 6.9.13-52 and 7.1.2-27, processing an extremely large JNX file on 32-bit platforms can cause an integer overflow, leading to a heap buffer over-write. This issue has been fixed in versions 6.9.13-52 and 7.1.2-27. |
| ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to 6.9.13-51 and 7.0.1-0 and above prior to 7.1.2-26, an invalid kernel can cause a heap buffer over-write when performing a morphology operation with a user supplied kernel. This issue has been fixed in versions 6.9.13-51 and 7.1.2-26. |
| In the Linux kernel, the following vulnerability has been resolved:
jfs: nlink overflow in jfs_rename
If nlink is maximal for a directory (-1) and inside that directory you
perform a rename for some child directory (not moving from the parent),
then the nlink of the first directory is first incremented and later
decremented. Normally this is fine, but when nlink = -1 this causes a
wrap around to 0, and then drop_nlink issues a warning.
After applying the patch syzbot no longer issues any warnings. I also
ran some basic fs tests to look for any regressions. |
| In the Linux kernel, the following vulnerability has been resolved:
i2c: rtl9300: ensure data length is within supported range
Add an explicit check for the xfer length to 'rtl9300_i2c_config_xfer'
to ensure the data length isn't within the supported range. In
particular a data length of 0 is not supported by the hardware and
causes unintended or destructive behaviour.
This limitation becomes obvious when looking at the register
documentation [1]. 4 bits are reserved for DATA_WIDTH and the value
of these 4 bits is used as N + 1, allowing a data length range of
1 <= len <= 16.
Affected by this is the SMBus Quick Operation which works with a data
length of 0. Passing 0 as the length causes an underflow of the value
due to:
(len - 1) & 0xf
and effectively specifying a transfer length of 16 via the registers.
This causes a 16-byte write operation instead of a Quick Write. For
example, on SFP modules without write-protected EEPROM this soft-bricks
them by overwriting some initial bytes.
For completeness, also add a quirk for the zero length.
