commit 58f1e0b6a4e6aa55621c6f01118994d01fd6f68c
Merge: f983e445 e7bcd3cc
Author: Alexander Epaneshnikov <aarnaarn2@gmail.com>
Date: Sun Dec 17 15:29:30 2023 +0300
tests: fix CVE crashes (#1846)
Fixes: #1823, #1824, #1825, #1826, #1827
- Add crash test and vectors provided by @SEU-SSL
- Disallow dummy/null voice load (that causes incorrect translator
initialization)
- Fix empty `phondata` file load (that causes unitialized memory access)
- Limit max word length for RemoveEnding (causes buffer overflow)
- Limit punctlist initialization from embedded commands (buffer
overflow)
- Fix unitialized pitch in wavegen (DBZ and indexing problems)
- Properly zeroize stack variables before use in TranslateClause and
SetWordStress
TODO (in nextup PR): add & fix more vectors from fuzzer.
