Multiple integer overflows in Christos Zoulas file before 5.02 allow user-assisted remote attackers to have an unspecified impact via a malformed compound document (aka cdf) file that triggers a buffer overflow.

The gnu regular expression code in file 4.20 allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted document with a large number of line feed characters, which is not well handled by OS/2 REXX regular expressions that use wildcards, as originally reported for AMaViS.
