CVE 描述
Sereal::Decoder versions before 5.005 for Perl allow heap out-of-bounds read via crafted input
Sereal::Decoder versions before 5.005 for Perl allow heap out-of-bounds read via crafted input. In Perl/Decoder/srl_decoder.c, srl_read_object() and srl_read_hash() process a COPY tag, a back-reference whose target byte the decoder re-decodes as a fresh tag. When that target byte matches the SHORT_BINARY pattern (an inline string whose length is encoded in the low bits of the tag), the resulting read is not bounded to precede the COPY tag's own offset and can run past the end of the input buffer. An attacker controlled COPY offset can land inside a previously decoded value rather than on a tag boundary, planting a byte that the decoder reads as a SHORT_BINARY tag and consuming up to 31 following bytes from the heap as a class name (OBJECT path) or hash key (HASH path).CVE 解決方案
Upgrade to Sereal::Decoder 5.005 or later.

EPSS
EPSS 是一種預測漏洞被利用可能性的評分模型。
EPSS 評分
EPSS 模型產生介於 0 到 1（0% 到 100%）之間的概率分數。分數越高，漏洞被利用的概率越大。
EPSS 百分位數
百分位數用於根據 EPSS 分數對 CVE 進行排名。例如，EPSS 評分在第 95 百分位的 CVE 比 95% 的其他 CVE 更有可能被利用。因此，百分位數用於比較某 CVE 的 EPSS 分數與其他 CVE 的相對位置。
