| 标题 | Open Babel 3.1.1 / master commit 889c3501 Memory Corruption |
|---|
| 描述 | Open Babel 3.1.1 (and the current master branch at commit 889c350) contains a vulnerability in the ZIP stream handling code (zipstreamimpl.h). When parsing certain compressed input files, the function zlib_stream::basic_unzip_streambuf<char>::underflow() invokes memcpy with overlapping source and destination buffers. Since memcpy is undefined for overlapping memory regions, this results in undefined behavior and can lead to memory corruption or a crash. A crafted input file can reliably trigger this condition, leading to denial-of-service and potentially opening the door for more severe memory corruption exploits. |
