Security Bulletin: Impacted IBM Optim for z/OS 1.0.0, 1.1.0 and 1.2.0 by vulnerabilities in jackc/Pgx, cloudflare/cfSSL, x/net

Summary IBM Optim for z/OS version 1.0.0, 1.1.0 and 1.2.0 depends on open-source packages jackc/Pgx, cloudflare/cfSSL and x/net which are affected by medium, high and critical severity vulnerabilities. IBM Optim for z/OS 2.0.0 resolves these vulnerabilities by upgrading the affected open-source...

golang.org/x/net/idna: golang: net/http: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing

A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname for example, xn--example-.com returns example.com instead of an error. Applications that validate the ASCII form then convert to Unicode may grant acce...

net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME

A flaw was found in the net package of Go golang, specifically when using the LookupCNAME function with the cgo DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name CNAME response. This can trigger a double-free of C memory, leading to a crash and a Denial of...

net/url: golang: golang net/url: Denial of Service from quadratic complexity in path resolution

A flaw was found in net/url, a component of golang. This vulnerability arises when resolving relative paths that contain numerous parent directory '..' segments. A remote attacker could exploit this by providing a specially crafted path, leading to quadratic time complexity and excessive memory...
