Title: Debian scratchbox2 Insecure Temporary File Creation Vulnerabilities
Severity: LOW
Description:
Debian scratchbox2 is a transparent cross-compiling environment.
Debian scratchbox2 creates temporary files in an insecure manner. Specifically, the following scripts are affected:
'scripts/dpkg-checkbuilddeps'
'scripts/sb2-check-pkg-mappings'
An attacker with local access could potentially exploit these issues to perform symbolic-link attacks, overwriting arbitrary files in the context of the affected application.
Successfully mounting a symlink attack may allow the attacker to delete or corrupt sensitive files, which may result in a denial of service. Other attacks may also be possible.
Debian scratchbox2 1.99.0.24-1 is vulnerable; other versions may also be affected.
Affected Products:
- Debian scratchbox2 1.99.0.24-1

- Debian: #496409 The possibility of attack with the help of symlinks in some Debian packa
