CyberRota Analysis
AI-GeneratedRsync versions prior to 3.5.0 are vulnerable to an out-of-bounds write that can lead to memory corruption through improper handling of file entries with the HLINKED flag when hard-link preservation is disabled. This vulnerability allows attackers to manipulate memory, potentially leading to arbitrary code execution or system instability. Organizations using affected versions of rsync should prioritize patching to mitigate the risk of exploitation.

Original NVD Description
rsync 3.0.0 before 3.5.0 contains an out-of-bounds write vulnerability that allows attackers to corrupt memory by triggering HLINK_BUMP processing on file entries with the FLAG_HLINKED flag set while the hard-link preservation option is inactive. Attackers can exploit the missing F_SUM field in the file_struct layout to access memory past the end of the allocated structure, corrupting adjacent heap or stack data.
