CVE-2025-2724
Description
A flaw was found in the libgsf package, affecting the sorting_key_copy function. It is possible to launch the attack on the local host, and manipulation of the Name argument can lead to out-of-bounds read.
Statement
This CVE has been marked as Rejected by the assigning CNA. The code maintainer explains that "the only way to get an object of type GsfMSOleSortingKey is via gsf_msole_sorting_key_new which adds that extra zero element".
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Memory
An attacker could get secret values such as cryptographic keys, PII, memory addresses, or other information that could be used in additional attacks.
Confidentiality
Technical Impact: Bypass Protection Mechanism
Out-of-bounds memory could contain memory addresses or other information that can be used to bypass ASLR and other protection mechanisms in order to improve the reliability of exploiting a separate weakness for code execution.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
An attacker could cause a segmentation fault or crash by causing memory to be read outside of the bounds of the buffer. This is especially likely when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string.
Other
Technical Impact: Varies by Context
The read operation could produce other undefined or unexpected results.
