CVE-2022-4450

一、漏洞信息
 漏洞编号：[CVE-2022-4450](https://nvd.nist.gov/vuln/detail/CVE-2022-4450)
 漏洞归属组件：[openresty-openssl111](https://gitee.com/src-openeuler/openresty-openssl111)
 漏洞归属的版本：OpenSSL3.0和1.1.1容易受到此问题的影响。OpenSSLasn1parse命令行应用程序也受此问题影响。
 CVSS V3.0分值：
  BaseScore：7.5 High
  Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
 漏洞简述：
  The function PEM_read_bio_ex() reads a PEM file from a BIO and parses anddecodes the  name  (e.g.  CERTIFICATE ), any header data and the payload data.If the function succeeds then the  name_out ,  header  and  data  arguments arepopulated with pointers to buffers containing the relevant decoded data. Thecaller is responsible for freeing those buffers. It is possible to construct aPEM file that results in 0 bytes of payload data. In this case PEM_read_bio_ex()will return a failure code but will populate the header argument with a pointerto a buffer that has already been freed. If the caller also frees this bufferthen a double free will occur. This will most likely lead to a crash. Thiscould be exploited by an attacker who has the ability to supply malicious PEMfiles for parsing to achieve a denial of service attack.The functions PEM_read_bio() and PEM_read() are simple wrappers aroundPEM_read_bio_ex() and therefore these functions are also directly affected.These functions are also called indirectly by a number of other OpenSSLfunctions including PEM_X509_INFO_read_bio_ex() andSSL_CTX_use_serverinfo_file() which are also vulnerable. Some OpenSSL internaluses of these functions are not vulnerable because the caller does not free theheader argument if PEM_read_bio_ex() returns a failure code. These locationsinclude the PEM_read_bio_TYPE() functions as well as the decoders introduced inOpenSSL 3.0.The OpenSSL asn1parse command line application is also impacted by this issue.

二、漏洞分析结构反馈
 影响性分析说明：
  The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and decodes the  name  (e.g.  CERTIFICATE ), any header data and the payload data. If the function succeeds then the  name_out ,  header  and  data  arguments are populated with pointers to buffers containing the relevant decoded data. The caller is responsible for freeing those buffers. It is possible to construct a PEM file that results in 0 bytes of payload data. In this case PEM_read_bio_ex() will return a failure code but will populate the header argument with a pointer to a buffer that has already been freed. If the caller also frees this buffer then a double free will occur. This will most likely lead to a crash. This could be exploited by an attacker who has the ability to supply malicious PEM files for parsing to achieve a denial of service attack. The functions PEM_read_bio() and PEM_read() are simple wrappers around PEM_read_bio_ex() and therefore these functions are also directly affected. These functions are also called indirectly by a number of other OpenSSL functions including PEM_X509_INFO_read_bio_ex() and SSL_CTX_use_serverinfo_file() which are also vulnerable. Some OpenSSL internal uses of these functions are not vulnerable because the caller does not free the header argument if PEM_read_bio_ex() returns a failure code. These locations include the PEM_read_bio_TYPE() functions as well as the decoders introduced in OpenSSL 3.0. The OpenSSL asn1parse command line application is also impacted by this issue.
