UBUNTU-CVE-2024-45236

An issue was discovered in Fort before 1.6.3. A malicious RPKI repository that descends from a trusted Trust Anchor can serve via rsync or RRDP a signed object containing an empty signedAttributes field. Fort accesses the set's elements without sanitizing it first. Because Fort is an RPKI Relying...

UBUNTU-CVE-2024-45234

An issue was discovered in Fort before 1.6.3. A malicious RPKI repository that descends from a trusted Trust Anchor can serve via rsync or RRDP an ROA or a Manifest containing a signedAttrs encoded in non-canonical form. This bypasses Fort's BER decoder, reaching a point in the code that panics...

SUSE CVE-2009-0591
