w3m through 0.5.3 is prone to an infinite recursion flaw in HTMLlineproc0 because the feed_table_block_tag function in table.c does not prevent a negative indent value.
w3m through 0.5.3 does not properly handle temporary files when the ~/.w3m directory is unwritable, which allows a local attacker to craft a symlink attack to overwrite arbitrary files.
The HTMLtagproc1 function in file.c in w3m before 0.5.3+git20161009 does not properly initialize values, which allows remote attackers to crash the application via a crafted html file, related to <dd> tags.
parsetagx.c in w3m before 0.5.3+git20161009 does not properly initialize values, which allows remote attackers to crash the application via a crafted html file, related to a <i> tag.
An issue was discovered in the Tatsuya Kinoshita w3m fork before 0.5.3-33. w3m allows remote attackers to cause a denial of service (infinite loop and resource consumption) via a crafted HTML page.
