VUL-0: CVE-2020-24741: libqt5-qtbase: qt: QLibrary loads libraries relative to CWD which could result in arbitrary code execution
Last modified: 2024-06-07 12:24:33 UTC
An issue has been fixed in Qt versions 5.14.1 and 5.12.7 where QLibrary attempts to load plugins relative to the working directory, allowing attackers to execute arbitrary code via crafted files.

I don't think Qt < 5.12.0 is not affected by this bug, because it does not search platform specific library locations. The fix commit mentions 5219c37f7c98f37f078fee00fe8ca35d83ff4f5d as the cause of the issue, which is only included in 5.12.0 and later. So this can be closed as INVALID FWICT.

I used the opensuse/leap:42.3 - :15.3 containers to validate that they're not affected. The exact reproducer of the bug report is to strace a Qt application using XCB, like: zypper in -y xvfb-run which libqt5-qttools strace && ( xvfb-run -a -s "+iglx +render" strace -fefile qdbusviewer-qt5 |& grep Xcursor ) and checking that nothing uses paths relative to the CWD. 42.3: Not loaded as plugin: [pid 655] open("/usr/lib64/libXcursor.so.1", O_RDONLY|O_CLOEXEC) = (no other CWD relative opens either) 15.0 and 15.1, absolute paths only: [pid 504] openat(AT_FDCWD, "/lib64/libXcursor.so.1", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) [pid 504] openat(AT_FDCWD, "/usr/lib64/libXcursor.so.1", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) On 15.2 and 15.3, it uses "haswell/", but with absolute paths, because 5.12.7 contains the fix already: [pid 619] openat(AT_FDCWD, "/lib64/haswell/x86_64/libXcursor.so.1", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) [pid 619] openat(AT_FDCWD, "/lib64/haswell/libXcursor.so.1", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) Reassigning to security team to close this as INVALID.
