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.

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.

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.
