CVE-2009-5029
Integer overflow in the __tzfile_read function in glibc before 2.15 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted timezone (TZ) file, as demonstrated using vsftpd.

Does this matter?
Lower severity and a low EPSS score (8.07%). Track it; it rarely justifies an emergency change on its own.
