CVE-2024-6874

libcurl's URL API function curlurlget offers punycode conversions, to and from IDN. Asking to convert a name that is exactly 256 bytes, libcurl ends up reading outside of a stack based buffer when built to use the macidn IDN backend. The conversion function then fills up the provided buffer exact...

CVE-2024-6197 freeing stack buffer in utf8asn1str

libcurl's ASN1 parser has this utf8asn1str function used for parsing an ASN.1 UTF-8 string. Itcan detect an invalid field and return error. Unfortunately, when doing so it also invokes free on a 4 byte localstack buffer. Most modern malloc implementations detect this error and immediately abort...

CVE-2024-6197

CVE-2024-6197 affects libcurl’s ASN.1 parser (utf8asn1str) where freeing a 4-byte local stack buffer on error can corrupt nearby stack memory depending on the malloc implementation; outcome most often is a crash, with remote exploitation not detailed in the provided documents. Connected sources c...

Internet Bug Bounty: curl: stack-buffer overread during punycode conversions

The vulnerability in libcurl's URL API function curlurlget was discovered, where it performed punycode conversions. When converting a 256-byte domain name, the function read outside of a stack-based buffer, potentially leaking adjacent stack memory as part of the converted string. The flaw was...

Internet Bug Bounty: libcurl: freeing stack buffer during x509 certificate parsing

The libcurl's ASN1 parser had a vulnerability in the utf8asn1str function used for parsing an ASN.1 UTF-8 string. The function could detect an invalid field and return an error, which would trigger a free of a 4-byte local stack buffer. This could lead to a crash or potential memory corruption,...

libcurl 安全漏洞

libcurl is a free and easy-to-use client-side URL transport library from the cURL open source. A security vulnerability exists in the libcurl URL API version 8.8.0, which stems from the fact that the function curlurlget reads outside of the stack-based buffer when processing IDN conversions,...

curl: CVE-2024-6874: macidn punycode buffer overread

The libcurl at commit 58772b0e082eda333e0a5fc8fb0bc7f17a3cd99c contained a stack-buffer overread in the function macidntoascii that could be triggered when the host of a URL was converted to punycode. The root cause was in the function uidnanameToASCIIUTF8, which left the output buffer unterminat...

CBL Mariner 2.0 Security Update: rust / tensorflow / cmake / mysql (CVE-2023-27537)

The version of rust / tensorflow / cmake / mysql installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-27537 advisory. - A double free vulnerability exists in libcurl 8.0.0 when sharing HSTS data betwee...

When doing HTTP(S) transfers libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send even when the `CURLOPT_POSTFIELDS` option has been set if the same handle previously was used to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the subsequent `POST` request. The problem exists in the logic for a reused handle when it is changed from a PUT to a POST.
