-----BEGIN PGP SIGNED MESSAGE-----
Insecure filename usage in cbrPager may allow for the remote execution of arbitrary code.
cbrPager is a comic book pager.
Mamoru Tasaka discovered that filenames of the image archives are not properly sanitized before being passed to decompression utilities like unrar and unzip, which use the system() libc library call.
A remote attacker could entice a user to open an archive with a specially crafted filename, resulting in arbitrary code execution with the privileges of the user running the application.
There is no known workaround at this time.
All cbrPager users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-misc/cbrpager-0.9.17"
[ 1 ] CVE-2008-2575
