Description Martin Prpič 2015-11-04 09:56:34 UTC

Various security flaws were found in potrace:

October 22, 2015: Release 1.13. Some critical bugs in the processing of BMP files were fixed. These bugs allowed the program to be crashed, or potentially to be abused in other ways, by feeding it specially crafted BMP files. Thanks to Tomasz Buchert and Agostino Sarubbo for reporting these bugs. Portability was improved for C99 and for MSVC++. Thanks to Peter Breitenlohner, Nelson Beebe, and Martin Gieseking for reporting portability issues.
