Name of the Vulnerable Software and Affected Versions
rsync versions 3.0.1 through 3.4.x
Description
An out-of-bounds write exists in the
read args() function. A malicious sender can corrupt adjacent heap memory by providing a crafted argument list. This occurs when the argument count fills the argv allocation exactly, causing the trailing NULL terminator to be written beyond the allocation boundary.Recommendations
Update rsync to version 3.5.0 or later.
