SUSE CVE-2026-10028

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...

OESA-2026-2561 glib-networking security update

glib-networking contains the implementations of certain GLib networking features that cannot be implemented directly in GLib itself because of their dependencies. Security Fixes: A flaw was found in glib-networking. A remote attacker can exploit this vulnerability by presenting a specially crafte...

curl: GnuTLS OCSP stapling accepts unrelated SingleResponse (no cert-ID binding)

Summary This report describes a variant of the publicly disclosed curl vulnerability CVE-2020-8286 OCSP stapling verification bypass, found in the GnuTLS TLS backend lib/vtls/gtls.c. The original CVE affected the NSS backend; this variant reproduces the same logical class of defect — accepting...

CVE-2026-10028 Glib-networking: infinite loop in glib-networking gnutls backend allows remote denial of service via circular certificate chain

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...

CVE-2026-10028

Affected software: glib-networking with the GnuTLS backend. Issue: a certificate verification path can loop indefinitely when presented with a specially crafted chain containing circular issuer relationships. Impact: unbounded traversal consumes CPU, causing denial of service of the affected proc...

curl: curl GnuTLS backend accepts a clientAuth-only certificate for HTTPS server authentication

Summary: When curl/libcurl is built with the GnuTLS backend, the current HTTPS server-certificate validation path verifies the trust chain and hostname but does not enforce TLS server Extended Key Usage semantics. As a result, a leaf certificate that chains to a trusted CA, matches the requested...

The vulnerability was exploited in Exim.

The developers of Exim introduced a vulnerability in the Exim Mail Transfer Agent versions prior to 4.99.3. This vulnerability involves a use-after-free in the BDAT body parsing process, specifically when certain GnuTLS backend configurations are used. An unauthorized attacker can exploit this...

CVE-2026-45185

Exim before 4.99.3, in certain GnuTLS configurations, has a remotely reachable use-after-free in the BDAT body parsing path. It is triggered when a client sends a TLS closenotify mid-body during a CHUNKING transfer, followed by a final cleartext byte on the same TCP connection. This can lead to...

CVE-2026-42225 GnuTLS backend silently skips certificate chain verification when verify_peer is false

PJSIP is a free and open source multimedia communication library written in C. Prior to version 2.17, on GnuTLS builds, the SIP TLS transport siptransporttls can accept connections with invalid or untrusted certificates even when the application explicitly enables certificate verification via...

curl: curl built with GnuTLS backend defaults to weak crypto parameters

Summary: Curl configured with GnuTLS backend --with-gnutls defaults using "NORMAL" as the base level of the library cryptographic security. From GnuTLS documentation: The message authenticity security level is of 64 bits or more, and the certificate verification profile is set to GNUTLSPROFILELOW...

SUSE CVE-2013-6422

The GnuTLS backend in libcurl 7.21.4 through 7.33.0, when disabling digital signature verification CURLOPTSSLVERIFYPEER, also disables the CURLOPTSSLVERIFYHOST check for CN or SAN host name fields, which makes it easier for remote attackers to spoof servers and conduct man-in-the-middle MITM...

SUSE CVE-2018-21029

systemd 239 through 245 accepts any certificate signed by a trusted certificate authority for DNS Over TLS. Server Name Indication SNI is not sent, and there is no hostname validation with the GnuTLS backend. NOTE: This has been disputed by the developer as not a vulnerability since hostname...

systemd 239 through 245 accepts any certificate signed by a trusted certificate authority for DNS Over TLS. Server Name Indication (SNI) is not sent and there is no hostname validation with the GnuTLS backend. NOTE: This has been disputed by the developer as not a vulnerability since hostname validation does not have anything to do with this issue (i.e. there is no hostname to be sent)
