Where:

From local network

Impact:

DoS, System access

Solution Status:

Vendor Patch

CVE Reference(s):

Description


Some vulnerabilities have been reported in CUPS, which can be exploited by malicious people to cause a DoS (Denial of Service) or to potentially compromise a vulnerable system.

1) A boundary error exists within the "cgiCompileSearch()" function in cgi-bin/search.c. This can be exploited to cause a heap-based buffer overflow via a specially crafted IPP request.

Successful exploitation may allow execution of arbitrary code, but requires that the vulnerable system is sharing printers on the network.

NOTE: If printer sharing is disabled, the vulnerability can only be exploited by malicious, local users.

2) A boundary error exists within the "gif_read_image()" function in filter/image-gif.c. This can be exploited to cause a buffer overflow via overly large "code_size" values in GIF image files.

This may be related to vulnerability #4 in:
SA21546

Successful exploitation may allow execution of arbitrary code.

The vulnerabilities are reported in version 1.3.6. Prior versions may also be affected.


Solution:
Update to version 1.3.7.

Provided and/or discovered by:
1) regenrecht, reported via iDefense.
2) Reported by the vendor.
