Libarchive: heap overflow oob read while parsing a tar archive contains a pax extended header

A flaw was found in libarchive. This vulnerability allows a remote attacker to trigger a heap overflow by providing a specially crafted tar archive. The issue occurs during the parsing of a PAX extended header containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation could lead to a denial of service, making the system unavailable, or potentially allow for arbitrary code execution, giving the attacker control over the affected system.

CWE-122 Heap-based Buffer Overflow

A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

CWE-805 Buffer Access with Incorrect Length Value

The product uses a sequential operation to read or write a buffer, but it uses an incorrect length value that causes it to access memory that is outside of the bounds of the buffer.
