Vulnerability Details

A stack-based buffer overflow was discovered in OpenBSD's libskey. In the file skeylogin.c, "pbuf - p" at lines 439 and 440 should be "p - pbuf", so the "pbuf - p < 4" test at line 439 always succeeds and the strncpy() at line 440 may overflow pbuf (if 2 * (p - pbuf) + 4 > 255 + 1, i.e. if the hostname is longer than 126 characters).
