Kernel panic - not syncing: UBSAN: panic_on_warn set. Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google Index 196694 is out of range for type 's8' (aka 'signed char')ĬPU: 1 PID: 109 Comm: jfsCommit Not tainted 6.6.0-rc3-syzkaller #0 UBSAN: array-index-out-of-bounds in fs/jfs/jfs_dmap.c:2867:6 In the Linux kernel, the following vulnerability has been resolved:įS:JFS:UBSAN:array-index-out-of-bounds in dbAdjTree Please note that this workaround must be carefully tested before it can be used. The vulnerability can likely temporarily be fixed by forking the go-saml project and adding the command line argument `-enabled-key-data` and specifying a value such as `x509` or `raw-x509-cert` when calling the `xmlsec1` binary in the verify function. Projects still using RobotsAndPencils/go-saml should move to another SAML library or alternatively remove support for SAML from their projects. an RSA key) directly embedded in the SAML token. That means an attacker can sign the SAML assertions themselves and provide the required public key (e.g. When `xmlsec1` is used without defining the enabled key data, the origin of the public key for the signature verification is, unfortunately, not restricted. This is due to how the `xmlsec1` command line tool is called internally to verify the signature of SAML assertions. RobotsAndPencils go-saml, a SAML client library written in Go, contains an authentication bypass vulnerability in all known versions.
