CVE-2026-54417
Last modified
CVE-2026-54417 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. An integer overflow in the mtar_next function in src/microtar.c in rxi microtar 0.1.0 allows a remote attacker to cause a denial of service (uncontrolled CPU consumption / infinite loop) via a crafted tar archive. mtar_next computes the offset to the next record as round_up(h.size, 512) + sizeof(mtar_raw_header_t) using 32-bit arithmetic.. EPSS estimates a 0.42% chance of exploitation in the next 30 days.
