CyberRota Analysis
AI-GeneratedThe GNU C Library versions 2.38 to 2.44 are vulnerable due to a flaw in the strfmon and strfmon_l functions, which can lead to buffer overflows when right-justified width padding is used with insufficiently sized destination buffers. This vulnerability could allow attackers to exploit applications that improperly handle user-influenced input, potentially leading to arbitrary code execution or data corruption. Organizations using affected versions of the GNU C Library, particularly those with custom applications that utilize these functions, should prioritize patching to mitigate potential risks.

Original NVD Description
Calling strfmon and strfmon_l in the GNU C Library version 2.38 to 2.44 can write past the end of the caller-supplied output buffer when a conversion uses right-justified width padding. Exploitation requires an application code path that calls strfmon or strfmon_l with right-justified width padding into a destination buffer that is large enough for the padding to succeed but too small for the internal memmove call. The field width or format may be attacker-influenced or a fixed susceptible pattern in the caller. At the time of publication, no network-facing application impact is known.
