Alpine: curl: security update to 7.58.0-r0
critical Tenable Self-Hosted Container Security Plugin ID 403977
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- libcurl 7.49.0 to and including 7.57.0 contains an out bounds read in code handling HTTP/2 trailers. It
was reported (https://github.com/curl/curl/pull/2231) that reading an HTTP/2 trailer could mess up future
trailers since the stored size was one byte less than required. The problem is that the code that creates
HTTP/1-like headers from the HTTP/2 trailer data once appended a string like `:` to the target buffer,
while this was recently changed to `: ` (a space was added after the colon) but the following math wasn't
updated correspondingly. When accessed, the data is read out of bounds and causes either a crash or that
the (too large) data gets passed to client write. This could lead to a denial-of-service situation or an
information disclosure if someone has a service that echoes back or uses the trailers for something.
