CVE-2026-70457

An out-of-bounds write vulnerability in rsync's parsesizearg function allows a remote attacker to cause memory corruption. The flaw is triggered when snprintf truncates a formatted size string, resulting in an incorrect memory array index. Exploitation can lead to a denial of service and...

miniupnpd_poc

Vulnérabilité de lecture hors limites dans Miniupnpd path supérieure à 526 octets. La cause racine est due à l'absence de validation de la valeur de retour de snprintf, car snprintf retourne la valeur du nombre d'octets qu'elle aurait pu copier, et non le nombre d'octets effectivement copiés. En...

SUSE CVE-2026-70457

rsync 3.2.3 before 3.5.0 contains an out-of-bounds write in parsesizearg where the return value of snprintf is used directly as an index into a .bss-segment array without bounds checking. When snprintf truncates the formatted size string, the return value equals the number of characters that woul...

Incorrect Calculation of Buffer Size

Overview Affected versions of this package are vulnerable to Incorrect Calculation of Buffer Size in the parsesizearg function. An attacker can cause memory corruption by providing specially crafted input that leads to an out-of-bounds write when the return value of snprintf is used as an array...
