Summary
A flaw was found in glib-networking where a specially crafted certificate chain with circular issuer relationships causes an infinite loop during certificate verification. This leads to excessive CPU consumption and denial of service for the affected process.
Risk Assessment
A remote attacker can exploit this vulnerability to cause a denial of service by crashing or significantly slowing down applications using glib-networking with the GnuTLS backend, disrupting service availability.
Recommendation
Update glib-networking to the latest patched version immediately. If an update is not available, consider temporarily disabling the GnuTLS backend or restricting access to affected applications.
Other vulnerabilities in glib-networking
See all- CVE-2025-60019Low
The OpenSSL backend in glib-networking fails to properly check the return values of memory allocation routines. An out-of-memory condition could potentially result in writing to an invalid memory location.
- CVE-2025-60018Medium
The OpenSSL backend in glib-networking fails to properly check the return value of a call to BIO_write(), resulting in an out-of-bounds read.
Original NVD description (English source)
A flaw was found in glib-networking. A remote attacker can exploit this vulnerability by presenting a specially crafted certificate chain to an application that uses glib-networking with the GnuTLS backend enabled and performs certificate verification. This crafted chain, which contains circular issuer relationships, can cause an infinite loop during certificate verification. The unbounded traversal consumes excessive CPU resources, leading to a denial of service for the affected process or worker.
