CVE-2025-4945

Summary

A flaw was found in the cookie parsing logic of the libsoup HTTP library, used in GNOME applications and other software. The vulnerability arises when processing the expiration date of cookies, where a specially crafted value can trigger an integer overflow. This may result in undefined behavior, allowing an attacker to bypass cookie expiration logic, causing persistent or unintended cookie behavior. The issue stems from improper validation of large integer inputs during date arithmetic operations within the cookie parsing routines.

Weaknesses

  • CWE-190: Integer Overflow or Wraparound

Workarounds

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.
