CVE-2009-2624 is a vulnerability of currently unknown severity. The huft_build function in inflate.c in gzip before 1.3.13 creates a hufts (aka huffman) table that is too small, which allows remote attackers to cause a denial of service (application crash or infinite loop) or possibly execute arbitrary code via a crafted archive. NOTE: this issue is caused by a CVE-2006-4334 regression.. EPSS estimates a 4.18% chance of exploitation in the next 30 days.
