CVE-2023-1999

一、漏洞信息
 漏洞编号：[CVE-2023-1999](https://nvd.nist.gov/vuln/detail/CVE-2023-1999)
 漏洞归属组件：[mozjs78](https://gitee.com/src-openeuler/mozjs78)
 漏洞归属的版本：78.15.0,78.4.0
 CVSS V3.0分值：
  BaseScore：5.3 Medium
  Vector：CVSS：3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N
 漏洞简述：
  A use-after-free/double-free vulnerability exists in libwebp. An attacker can exploit the ApplyFiltersAndEncode() function to loop through freeing best.bw and assigning the best pointer to trial. The second loop returns 0 due to an out-of-memory error in the VP8 encoder, while the pointer remains assigned to trial, causing AddressSanitizer to attempt a double-free.
