CVE-2024-6874
|
Summary |
libcurl's URL API function
[curl_url_get()](https://curl.se/libcurl/c/curl_url_get.html) offers punycode
conversions, to and from IDN. Asking to convert a name that is exactly 256
bytes, libcurl ends up reading outside of a stack based buffer when built to
use the *macidn* IDN backend. The conversion function then fills up the
provided buffer exactly - but does not null terminate the string.
This flaw can lead to stack contents accidently getting returned as part of
the converted string. |

-
Infiltration of Hardware Development Environment
An attacker, leveraging the ability to manipulate components of primary support systems and tools within the development and production environments, inserts malicious software within the hardware and/or firmware development environment. The infiltration purpose is to alter developed hardware components in a system destined for deployment at the victim's organization, for the purpose of disruption or further compromise.
-
Overread Buffers
An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
