Уязвимость реализации функции read_header() архиватора GNU Tar, позволяющая нарушителю вызвать отказ в обслуживании

Уязвимость функции from_header (list.c) архиватора GNU Tar, связанная с чтением за пределами памяти, позволяющая нарушителю получить доступ к конфиденциальным данным

A flaw was found in the src/list.c of tar 1.33 and earlier. This flaw allows an attacker who can submit a crafted input file to tar to cause uncontrolled consumption of memory. The highest threat from this vulnerability is to system availability.

GNU Tar through 1.34 has a one-byte out-of-bounds read that results in use of uninitialized memory for a conditional jump. Exploitation to change the flow of control has not been demonstrated. The issue occurs in from_header in list.c via a V7 archive in which mtime has approximately 11 whitespace characters.
