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):

An attacker who submits a crafted tar file with size in header struct being 0 may be able to trigger an calling of malloc(0) for a variable gnu_longlink, causing an out-of-bounds read.(CVE-2021-33643)

An attacker who submits a crafted tar file with size in header struct being 0 may be able to trigger an calling of malloc(0) for a variable gnu_longname, causing an out-of-bounds read.(CVE-2021-33644)

The thread() function doesn’t free a variable t->thbuf.gnu_longlink after allocating memory, which may cause a memory leak.(CVE-2021-33645)

The thread() function doesn’t free a variable t->thbuf.gnu_longname after allocating memory, which may cause a memory leak.(CVE-2021-33646)
