DEBIAN-CVE-2024-6197

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...

AZL-49664 CVE-2024-6874 affecting package cmake for versions less than 3.30.3-2

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...

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,...
