A stack-based buffer overflow was found in the zsh command interpreter. An attacker could use this flaw to cause a denial of service (zsh crash), when providing a specially-crafted string as input to the zsh shell (CVE-2009-1214, CVE-2009-1215). The updated packages have been patched to prevent this. Affected: 2008.1, 2009.0, Corporate 3.0, Corporate 4.0
