  "description": "Issue summary: Processing some specially crafted ASN.1 object identifiersordata containing them may be very slow.Impact summary: Applications that use OBJ_obj2txt() directly, or use any ofthe OpenSSL subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS with nomessagesize limit may experience notable to very long delays when processing thosemessages, which may lead to a Denial of Service.An OBJECT IDENTIFIER is composed of a series of numbers - sub-identifiers -most of which have no size limit.  OBJ_obj2txt() may be used to translatean ASN.1 OBJECT IDENTIFIER given in DER encoding form (using the OpenSSLtype ASN1_OBJECT) to its canonical numeric text form, which are thesub-identifiers of the OBJECT IDENTIFIER in decimal form, separated byperiods.When one of the sub-identifiers in the OBJECT IDENTIFIER is very large(these are sizes that are seen as absurdly large, taking up tens orhundredsof KiBs), the translation to a decimal number in text may take a very longtime.  The time complexity is O(n^2) with \u0027n\u0027 being the size of thesub-identifiers in bytes (*).With OpenSSL 3.0, support to fetch cryptographic algorithms using names /identifiers in string form was introduced.  This includes using OBJECTIDENTIFIERs in canonical numeric text form as identifiers for fetchingalgorithms.Such OBJECT IDENTIFIERs may be received through the ASN.1 structureAlgorithmIdentifier, which is commonly used in multiple protocols tospecifywhat cryptographic algorithm should be used to sign or verify, encrypt ordecrypt, or digest passed data.Applications that call OBJ_obj2txt() directly with untrusted data areaffected, with any version of OpenSSL.  If the use is for the mere purposeof display, the severity is considered low.In OpenSSL 3.0 and newer, this affects the subsystems OCSP, PKCS7/SMIME,CMS, CMP/CRMF or TS.  It also impacts anything that processes X.509certificates, including simple things like verifying its signature.The impact on TLS is relatively low, because all versions of OpenSSL have a100KiB limit on the peer\u0027s certificate chain.  Additionally, this onlyimpacts clients, or servers that have explicitly enabled clientauthentication.In OpenSSL 1.1.1 and 1.0.2, this only affects displaying diverse objects,such as X.509 certificates.  This is assumed to not happen in such a waythat it would cause a Denial of Service, so these versions are considerednot affected by this issue in such a way that it would be cause forconcern,and the severity is therefore considered low.",
