CVE-2009-1391

Off-by-one error in the inflate function in Zlib.xs in Compress::Raw::Zlib
Perl module before 2.017, as used in AMaViS, SpamAssassin, and possibly
other products, allows context-dependent attackers to cause a denial of
service (hang or crash) via a crafted zlib compressed stream that triggers
a heap-based buffer overflow, as exploited in the wild by
Trojan.Downloader-71014 in June 2009.
