CVSS 9.1 · Critical EPSS 2,6%
Kerentanan Out-of-bounds Read pada freebsd libfetch. Skor CVSS 3.1 9.1 (Critical) menurut NVD.
libfetch before 2021-07-26, as used in apk-tools, xbps, and other products, mishandles numeric strings for the FTP and HTTP protocols. The FTP passive mode implementation allows an out-of-bounds read because strtol is used to parse the relevant numbers into address bytes. It does not check if the line ends prematurely. If it does, the for-loop condition checks for the '\0' terminator one byte too late.
