Summary

libtar security update

Details

Libtar is a C library for manipulating POSIX tar files. It handles adding and extracting files to/from a tar archive. Requires gcc, make, and zlib.

Security Fix(es):

After tarclose(), libtar.c releases the memory pointed to by pointer t. After tarclose() is called in the list() function, it continues to use pointer t: freelonglinklongname(t->th_buf) . As a result, the released memory is used (use-after-free).(CVE-2021-33640)
