{"id":"UBUNTU-CVE-2024-7264","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 a `strlen()` 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](https://curl.se/libcurl/c/CURLINFO_CERTINFO.html) is used.","modified":"2026-04-22T18:53:00.403225Z","published":"2024-07-31T00:00:00Z","related":["USN-6944-1","USN-6944-2"],"upstream":["CVE-2024-7264"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-7264"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-7264"},{"type":"REPORT","url":"https://curl.se/docs/CVE-2024-7264.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6944-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6944-2"}],"affected":[{"package":{"name":"curl","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/curl@7.35.0-1ubuntu2.20+esm18?arch=source&distro=trusty/esm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.35.0-1ubuntu2.20+esm18"}]}],"versions":["7.32.0-1ubuntu1","7.33.0-1ubuntu1","7.34.0-1ubuntu1","7.35.0-1ubuntu1","7.35.0-1ubuntu2","7.35.0-1ubuntu2.1","7.35.0-1ubuntu2.2","7.35.0-1ubuntu2.3","7.35.0-1ubuntu2.5","7.35.0-1ubuntu2.6","7.35.0-1ubuntu2.7","7.35.0-1ubuntu2.8","7.35.0-1ubuntu2.9","7.35.0-1ubuntu2.10","7.35.0-1ubuntu2.11","7.35.0-1ubuntu2.12","7.35.0-1ubuntu2.13","7.35.0-1ubuntu2.14","7.35.0-1ubuntu2.15","7.35.0-1ubuntu2.16","7.35.0-1ubuntu2.17","7.35.0-1ubuntu2.19","7.35.0-1ubuntu2.20","7.35.0-1ubuntu2.20+esm2","7.35.0-1ubuntu2.20+esm3","7.35.0-1ubuntu2.20+esm4","7.35.0-1ubuntu2.20+esm5","7.35.0-1ubuntu2.20+esm6","7.35.0-1ubuntu2.20+esm7","7.35.0-1ubuntu2.20+esm8","7.35.0-1ubuntu2.20+esm9","7.35.0-1ubuntu2.20+esm10","7.35.0-1ubuntu2.20+esm11","7.35.0-1ubuntu2.20+esm12","7.35.0-1ubuntu2.20+esm13","7.35.0-1ubuntu2.20+esm14","7.35.0-1ubuntu2.20+esm15","7.35.0-1ubuntu2.20+esm16","7.35.0-1ubuntu2.20+esm17"],"ecosystem_specific":{"binaries":[{"binary_version":"7.35.0-1ubuntu2.20+esm18","binary_name":"curl"},{"binary_version":"7.35.0-1ubuntu2.20+esm18","binary_name":"libcurl3"},{"binary_version":"7.35.0-1ubuntu2.20+esm18","binary_name":"libcurl3-gnutls"},{"binary_version":"7.35.0-1ubuntu2.20+esm18","binary_name":"libcurl3-nss"}],"availability":"Available
