AlmaLinux 9 : skopeo (ALSA-2024:1149)

medium Nessus Plugin ID 191686

Synopsis

The remote AlmaLinux host is missing a security update.

Description

The remote AlmaLinux 9 host has packages installed that are affected by a vulnerability as referenced in the ALSA-2024:1149 advisory.

 - A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response body to read many more bytes from the network than are in the body. A malicious HTTP client can further exploit this to cause a server to automatically read a large amount of data (up to about 1GiB) when a handler fails to read the entire body of a request. Chunk extensions are a little-used HTTP feature which permit including additional metadata in a request or response body sent using the chunked encoding. The net/http chunked encoding reader discards this metadata. A sender can exploit this by inserting a large metadata segment with each byte transferred. The chunk reader now produces an error if the ratio of real body to encoded bytes grows too small. (CVE-2023-39326)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected skopeo and / or skopeo-tests packages.
