SUSE CVE-2026-13713

YAML::Syck versions before 1.47 for Perl allow a use-after-free and double-free via an anchor node freed while still on the parser value stack. In the bundled libsyck, when an anchor name is redefined or removed, syckhdlraddanchor and syckhdlrremoveanchor free the node stored under that name with...

SUSE CVE-2026-57075

YAML::Syck versions before 1.47 for Perl allow an out-of-bounds read via a signed-char lookup-table index in syckbase64dec. The base64 decoder in the bundled libsyck indexes the 256-entry static table b64xtable with a signed char, so any !!binary byte = 0x80 sign-extends to a negative index and...

SUSE CVE-2026-57076

YAML::Syck versions before 1.47 for Perl allow a heap use-after-free via an anchor name reused as an anchors-table key in syckhdlraddanchor. In the bundled libsyck an anchor name allocated by syckstrndup is stored both as node-anchor, freed when the node is freed, and as the key in the parser's...

SUSE CVE-2026-57077

YAML::Syck versions before 1.47 for Perl allow an out-of-bounds read via an unbounded newline scan in newlinelen. In the bundled libsyck newlinelen and isnewline dereference the scan pointer, and the following byte for a "\r\n" pair, with no NUL-terminator or bounds check. During block-scalar...

CVE-2026-57076

A flaw was found in YAML::Syck. An attacker could exploit a heap use-after-free vulnerability by providing a specially crafted YAML document that reuses an anchor name as an anchors-table key. This flaw causes the software to read freed heap memory, which may lead to information disclosure or...

CVE-2026-57077

A flaw was found in YAML::Syck. An out-of-bounds read vulnerability exists due to an unbounded newline scan during block-scalar lexing. A remote attacker could exploit this by providing a specially crafted YAML document, leading to potential information disclosure. This issue is an incomplete fix...

CVE-2026-57075

A flaw was found in YAML::Syck. An out-of-bounds read vulnerability exists in the base64 decoder, specifically in the syckbase64dec function. This occurs because the decoder uses a signed character to index a lookup table, allowing specially crafted !!binary YAML nodes with high-bit bytes to caus...
