### Summary A memory-safety vulnerability in Open Babel's Gaussian output parser allowed an out-of-bounds write into the `translationVectors[]` array when reading a crafted input file. ### Details The Gaussian reader stored periodic-cell translation vectors into a fixed-size `translationVectors[]` array. A malformed input could push more vectors than the array had slots, causing a write past the end of the array. This is one of five `translationVectors[]` OOB writes across formats (Gaussian,
