Alpine: multiple w3m packages: security update to 0.5.3_git20241203-r0

high Tenable Self-Hosted Container Security Plugin ID 427838

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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-2018-6198)

- 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. (CVE-2018-6196)

- w3m through 0.5.3 is prone to a NULL pointer dereference flaw in formUpdateBuffer in form.c.
(CVE-2018-6197)

- There is an out-of-bounds write in checkType located in etc.c in w3m 0.5.3. It can be triggered by sending
a crafted HTML file to the w3m binary. It allows an attacker to cause Denial of Service or possibly have
unspecified other impact. (CVE-2022-38223)
