Buffer Overwrite via Missing NUL in Solaris nvlist Array (CVE-202445288)
CVE-2024-45288 Published on September 5, 2024
Multiple vulnerabilities in libnv
A missing null-termination character in the last element of an nvlist array string can lead to writing outside the allocated buffer.
Vulnerability Analysis
CVE-2024-45288 is exploitable with local system access, and does not require authorization privileges or user interaction. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to be very high.
Weakness Types
Improper Null Termination
The software does not terminate or incorrectly terminates a string or array with a null character or equivalent terminator. Null termination errors frequently occur in two different ways. An off-by-one error could cause a null to be written out of bounds, leading to an overflow. Or, a program could use a strncpy() function call incorrectly, which prevents a null terminator from being added at all. Other scenarios are possible.
What is a Memory Corruption Vulnerability?
The software writes data past the end, or before the beginning, of the intended buffer. Typically, this can result in corruption of data, a crash, or code execution. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent write operation then produces undefined or unexpected results.
CVE-2024-45288 has been classified to as a Memory Corruption vulnerability or weakness.
