Advisory Updated Date: 2023-01-24 21:25 Pacific
Severity:
Medium
Issue Overview:
GNU cpio through 2.13 allows attackers to execute arbitrary code via a crafted pattern file, because of a dstring.c ds_fgetstr integer overflow that triggers an out-of-bounds heap write. NOTE: it is unclear whether there are common cases where the pattern file, associated with the -E option, is untrusted data. (CVE-2021-38185)
