NixOS vulnerability analysis and mitigation
Overview
An issue was discovered in PSPP 1.6.2 that contains a heap-based buffer overflow vulnerability in the function readbytesinternal in utilities/pspp-dump-sav.c. This vulnerability was discovered in September 2022 and affects PSPP version 1.6.2 (NVD, Savannah Bug).
Technical details
The vulnerability exists in the readbytesinternal function within the utilities/pspp-dump-sav.c file. When processing certain input data, the function performs a buffer operation without proper size validation, leading to a heap-based buffer overflow. The issue was confirmed through ASan (AddressSanitizer) testing which showed a WRITE overflow of size 5 bytes beyond the allocated buffer region (Savannah Bug).
Impact
The vulnerability allows attackers to cause a denial of service (application crash) or potentially have unspecified other impact through specially crafted input (NVD).
Mitigation and workarounds
The issue has been marked as fixed in the bug tracker. The developer implemented a fix by preventing the program from being installed, noting that the software had limited usage (Savannah Bug).
