✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: Currently no mitigation is available for this vulnerability. Workaround: To mitigate the risk associated with this libsoup vulnerability, Red Hat recommends avoiding interactions between client applications using the libsoup library and untrusted or compromised HTTP servers until a patched version of libsoup is deployed. Users and administrators should monitor their systems for suspicious HTTP activity and apply vendor updates as soon as a fix becomes available to prevent manipulation of cookie expiration logic that could lead to unexpected behavior or policy circumvention. Workaround: To mitigate this issue, Red Hat recommends avoiding the use of libsoup with untrusted or unauthenticated multipart HTTP message sources until updated packages are available. Administrators can deploy application-level filters or HTTP proxies that reject malformed multipart requests. It is strongly advised to apply vendor-supplied patches as soon as they are released to address this integer underflow vulnerability and restore the stability of affected services. Workaround: Mitigation for this issue is either not available or the currently available options don’t meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to a widespread installation base, or stability. It is strongly recommended to apply vendor-supplied patches once available. Workaround: No mitigation is currently available for this vulnerability. Workaround: Currently, no mitigation was found for this vulnerability. Workaround: Currently, no mitigation is available for this vulnerability.
