| CVE-2021-33643 | Cri | 0.59 | 9.1 | 0.02 | Aug 10, 2022 | 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-2021-33644 | Hig | 0.53 | 8.1 | 0.01 | Aug 10, 2022 | 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-2021-33646 | Hig | 0.49 | 7.5 | 0.02 | Aug 10, 2022 | The th_read() function doesn’t free a variable t->th_buf.gnu_longname after allocating memory, which may cause a memory leak. | ||
| CVE-2021-33645 | Hig | 0.49 | 7.5 | 0.02 | Aug 10, 2022 | The th_read() function doesn’t free a variable t->th_buf.gnu_longlink after allocating memory, which may cause a memory leak. | ||
| CVE-2013-4420 | 0.00 | — | 0.03 | Feb 20, 2014 | Multiple directory traversal vulnerabilities in the (1) tar_extract_glob and (2) tar_extract_all functions in libtar 1.2.20 and earlier allow remote attackers to overwrite arbitrary files via a .. (dot dot) in a crafted tar file. | |||
| CVE-2013-4397 | 0.00 | — | 0.05 | Oct 17, 2013 | Multiple integer overflows in the th_read function in lib/block.c in libtar before 1.2.20 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long (1) name or (2) link in an archive, which triggers a heap-based buffer overflow. |
