CVE-2023-1906
説明
A heap-based buffer overflow was found in ImageMagick's ImportMultiSpectralQuantum() function in MagickCore/quantum-import.c. This issue could allow an attacker to pass a specially crafted file to convert, triggering an out-of-bounds read error, which could cause an application to crash and result in a denial of service.
CVSS (Common Vulnerability Scoring System) のスコアの詳細
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
以下の CSVV メトリクスおよびスコアは予備的で、再検討の対象となります。

脆弱性の原因 (CWE) の理解
Confidentiality
Technical Impact: Read Memory
An attacker could get secret values such as cryptographic keys, PII, memory addresses, or other information that could be used in additional attacks.
Confidentiality
Technical Impact: Bypass Protection Mechanism
Out-of-bounds memory could contain memory addresses or other information that can be used to bypass ASLR and other protection mechanisms in order to improve the reliability of exploiting a separate weakness for code execution.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
An attacker could cause a segmentation fault or crash by causing memory to be read outside of the bounds of the buffer. This is especially likely when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string.
Other
Technical Impact: Varies by Context
The read operation could produce other undefined or unexpected results.
謝辞
Red Hat would like to thank Vikas Anil Sharma for reporting this issue.
