#

Summary A memory-safety vulnerability in Open Babel's ORCA parser allowed an

out-of-bounds write when reading a crafted input file.

Details A second variant of the nAtoms out-of-bounds write in the ORCA

reader: a different malformed-input path produced the same class of write past the end of the destination buffer.

file formats; it is shipped by Linux distributions and embedded in services that may parse untrusted input.
