- Summary
- ASN.1 date parser overread
- Details
-
libcurl's ASN1 parser code has the
GTime2str()function, used for parsing an ASN.1 Generalized Time field. If given an syntactically incorrect field, the parser might end up using -1 for the length of the time fraction, leading to astrlen()getting performed on a pointer to a heap buffer area that is not (purposely) null terminated.This flaw most likely leads to a crash, but can also lead to heap contents getting returned to the application when CURLINFO_CERTINFO is used.
