CVE-2024-25126

A denial of service (DoS) vulnerability was found in rubygem-rack in how it parses Content-Type. Carefully crafted content type headers can cause Rack’s media type parser to take much longer than expected, leading to a possible denial of service vulnerability.

5.3 (Medium)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
CWE-1333 - Inefficient Regular Expression Complexity
Vendor Fix For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 https://access.redhat.com/errata/RHSA-2024:2953
Workaround No mitigation is currently available for this vulnerability. The recommendation is to perform updates as soon as they are available.
CVE-2024-26141

A denial of service (DoS) vulnerability was found in rubygem-rack in how it parses Range Header. Carefully crafted range headers can cause a server to respond with an unexpectedly large response. Responding with large responses could lead to a denial of service issue.
