ruzstd is vulnerable to Out-of-bounds Read
80
High Risk
This Affects:
ruzstdTL;DR
Affected versions of ruzstd miscalculate the length of the allocated and initialized section of its internal RingBuffer, leading to uninitialized or out-of-bounds reads in the copy_bytes_overshooting function. This vulnerability allows up to 15 bytes of uninitialized memory to be read and potentially written into the output when decompressing a specially crafted archive. If exploited, this issue may result in sensitive memory contents being included in the decompressed data. This leakage can occur multiple times during the processing of a single archive, increasing the potential exposure of confidential information.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
