CVE-2015-1473 is a denial-of-service vulnerability in the GNU C Library (glibc) affecting versions prior to 2.21, including Canonical Ubuntu Linux. The flaw, residing in the ADDW macro within stdio-common/vfscanf.c, stems from improper data-type size consideration when using the alloca function during wscanf calls. This can lead to a segmentation fault or memory corruption via a long line with wide characters. With a CVSS score of 6.4, this vulnerability is rated as medium severity, indicating a network-exploitable attack with low complexity, requiring no authentication, and potentially leading to partial integrity and availability impacts. The EPSS score is very low (0.00449), suggesting a minimal likelihood of exploitation. There is no evidence of active exploitation, no known exploit code in Metasploit, Nuclei, or ExploitDB, and it is not listed in CISA's KEV catalog. Community discussion and media coverage are also absent, indicating a lack of widespread attention or exploitation.
