• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description GLSAMaker/CVETool Bot 2018-01-25 16:06:48 UTC]

CVE-2018-6198 (https://nvd.nist.gov/vuln/detail/CVE-2018-6198):
  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.

CVE-2018-6197 (https://nvd.nist.gov/vuln/detail/CVE-2018-6197):
  w3m through 0.5.3 is prone to a NULL pointer dereference flaw in
  formUpdateBuffer in form.c.

CVE-2018-6196 (https://nvd.nist.gov/vuln/detail/CVE-2018-6196):
  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.
