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.
Changelog:
