CVE-2024-7264 is an out-of-bounds read vulnerability in libcurl's ASN.1 parser. The flaw is in the GTime2str() function, which processes ASN.1 Generalized Time fields. When the parser is given a syntactically malformed Generalized Time value, it can incorrectly use -1 as the length of the time-fraction component. This can cause strlen() to operate on a pointer into a heap buffer that is not intentionally null-terminated. The resulting read past the intended buffer boundary can most likely crash the process and, in some cases, expose adjacent heap memory contents to the application when certificate information retrieval is enabled through CURLINFO_CERTINFO.

What an attacker gets, and what they’ve been doing with it.
CURLINFO_CERTINFO, the flaw can also disclose unintended heap contents to the calling application, creating an information disclosure condition. The available information indicates memory disclosure rather than code execution.If you can’t patch tonight, do this now.
CURLINFO_CERTINFO in affected applications. Limit processing of attacker-controlled TLS certificate data until patched. These measures are only partial mitigations and do not replace upgrading to a fixed version.Patch, then assume compromise.
