Alpine: multiple wget packages: security update to 1.19.2-r0

high Tenable Self-Hosted Container Security Plugin ID 424674

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - The retr.c:fd_read_body() function is called when processing OK responses. When the response is sent
 chunked in wget before 1.19.2, the chunk parser uses strtol() to read each chunk's length, but doesn't
 check that the chunk length is a non-negative number. The code then tries to read the chunk in pieces of
 8192 bytes by using the MIN() macro, but ends up passing the negative chunk length to retr.c:fd_read(). As
 fd_read() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fd_read()
 with a completely attacker controlled length argument. The attacker can corrupt malloc metadata after the
 allocated buffer. (CVE-2017-13090)
