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 tar_close(), libtar.c releases the memory pointed to by pointer t. After tar_close() is called in the list() function, it continues to use pointer t: free_longlink_longname(t->th_buf) . As a result, the released memory is used (use-after-free).(CVE-2021-33640) An update for libtar is now available for openEuler-22.03-LTS-SP1. openEuler Security has rated this update as having a security impact of medium.
