Oracle Linux 8:virt:ol (ELSA-2020-2774)

medium Nessus Plugin ID 138202

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 8 主機中安裝的套件受到 ELSA-2020-2774 公告中提及的多個弱點影響。

- 在 QEMU 4.1.0中所使用的 libslirp 4.2.0 中,tcp_subr.c 會誤用 snprintf 傳回值,進而在之後的程式碼中導致緩衝區溢位。(CVE-2020-8608)

- 在 QEMU 4.1.0 中,ui/vnc-enc-zrle.c 的 zrle_compress_data 在 VNC 中斷作業期間會發生記憶體洩漏問題,這是因為 libz 遭到誤用,導致 deflateInit2 中配置的記憶體未在 deflateEnd 中釋放。(CVE-2019-20382)

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。
