Low risk7th percentile - higher than 7% of all known CVEs
Summary
Data::Buffer::Shared before version 0.05 for Perl creates a world-readable mmap backing file (mode 0644) and opens it without O_NOFOLLOW. A local attacker can read IPC data or use a symlink to redirect the open.
Risk Assessment
A local user can access IPC data of other processes, compromising confidentiality of inter-process communication.
Recommendation
Update the Data::Buffer::Shared module to version 0.05 or later.

Original NVD description (English source)
Data::Buffer::Shared versions before 0.05 for Perl create a world-readable mmap backing file and open it without O_NOFOLLOW. The segment is created in buf_generic.h with open(path, O_RDWR|O_CREAT|O_EXCL, 0666). O_EXCL blocks a pre-seeded file on create, but the mode is 0666, so under the default umask 022 the file is created mode 0644 (world-readable), and O_NOFOLLOW is absent, so a symlink planted at the path is followed when the segment is attached. A "Shared" segment naturally lives in a shared directory such as /tmp or /dev/shm, where any local user can read the IPC payloads stored in the world-readable segment, and a pre-planted symlink at the path redirects the open to another file.
