CVE-2009-5029

Publication date 19 December 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
