Andrew V. Samoilov has noticed that several bugfixes which were applied to the source by upstream developers of mc, the midnight commander, a file browser and manager, were not backported to the current version of mc that Debian ships in their stable release. The Common Vulnerabilities and Exposures Project identifies the following vulnerabilities:

Multiple format string vulnerabilities

Multiple buffer overflows

One infinite loop vulnerability

Denial of service via corrupted section header

Denial of service via null dereference

Freeing unallocated memory

Denial of service via use of already freed memory

Denial of service via manipulating non-existing file handles

Unintended program execution via insecure filename quoting

Denial of service via a buffer underflow

For the stable distribution (woody) these problems have been fixed in version 4.5.55-1.2woody5.

For the unstable distribution (sid) these problems should already be fixed since they were backported from current versions.

We recommend that you upgrade your mc package.
