Oracle Linux 6:perl (ELSA-2021-9238)

high Nessus Plugin ID 149822

概要

遠端 Oracle Linux 主機缺少一個或多個安全性更新。

說明

遠端 Oracle Linux 6 主機中安裝的套件受到 ELSA-2021-9238 公告中提及的多個弱點影響。

- 32 位元平台上的 Perl 5.30.3 之前版本允許發生堆積型緩衝區溢位,這是巢狀規則運算式數量詞中存在整數溢位問題所致。(CVE-2020-10543)

- Perl 5.30.3 之前版本中存在整數溢位問題,這與程式錯誤處理「PL_regkind [OP(n)] == NOTHING」情況有關。特別建構的規則運算式可導致位元組程式碼格式錯誤,並可能造成指令插入。(CVE-2020-10878)

- 在 Perl 5.30.3 之前的版本中,regcomp.c 允許透過特別建構的規則運算式造成緩衝區溢位,這是遞迴 S_study_chunk 呼叫所致。(CVE-2020-12723)

請注意,Nessus 並未測試此問題,而是僅依據應用程式自我報告的版本號碼。
