Title: BitMover BitKeeper Local Temporary File Race Condition Vulnerability
Severity: MODERATE
Description:
BitKeeper is a source code management system by BitMover. It is available for Unix, Linux, and Microsoft Windows operating systems.
A problem with BitKeeper may make local symbolic link attacks possible.
It has been reported that BitKeeper is vulnerable to a race condition error. Under some circumstances, BitKeeper creates files in the temporary directory. However, it may be possible to create a symbolic link in a crucial point of program execution that would result in the overwriting of files at the end of the link.
The program does not properly open the temporary file. Rather than performing the check and opening the file all in one function, the program first checks, then in a seperate function opens the file. This creates a window of attack that could result in the overwriting of files that are write-accessible to the BitKeeper process.
