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.(CVE-2025-25724)

It was discovered that the libarchive bsdunzip utility incorrectly handled certain ZIP archive files. If a user or automated system were tricked into processing a specially crafted ZIP archive, an attacker could use this issue to cause libarchive to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04. (CVE-2025-1632)
