Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds write (CVE-ID: CVE-2026-19499)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: 8.4 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:L/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to write beyond a caller-supplied output buffer.

The vulnerability exists due to a buffer overflow in strfmon and strfmon_l when processing a conversion with right-justified width padding. A remote attacker can supply a crafted format or field width to write beyond a caller-supplied output buffer.

Exploitation requires a destination buffer large enough for padding but too small for the internal memmove operation.
