  • Published2025-03-02

Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

list_item_verbose in tar/util.c in libarchive through 3.7.7 does not check an strftime return value, which can lead to a denial of service or unspecified other impact via a crafted TAR archive that is read with a verbose value of 2. For example, the 100-byte buffer may not be sufficient for a custom locale.
