If cookie state is written into a cookie jar file that is later read back and used for subsequent requests, a malicious HTTP server can inject new cookies for arbitrary domains into said cookie jar. CVE-2016-8615 SUSE Studio Onsite 1.3:libcurl-devel-7.19.7-1.20.47.2 low 5.8 AV:N/AC:M/Au:N/C:P/I:P/A:N To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2016/suse-su-20162700-1/ https://www.suse.com/security/cve/CVE-2016-8615.html CVE-2016-8615 https://bugzilla.suse.com/1005633 SUSE Bug 1005633 A flaw was found in curl before version 7.51.0 When re-using a connection, curl was doing case insensitive comparisons of user name and password with the existing connections. This means that if an unused connection with proper credentials exists for a protocol that has connection-scoped credentials, an attacker can cause that connection to be reused if s/he knows the case-insensitive version of the correct password. CVE-2016-8616 SUSE Studio Onsite 1.3:libcurl-devel-7.19.7-1.20.47.2 low 1.9 AV:L/AC:M/Au:N/C:P/I:N/A:N To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2016/suse-su-20162700-1/ https://www.suse.com/security/cve/CVE-2016-8616.html CVE-2016-8616 https://bugzilla.suse.com/1005634 SUSE Bug 1005634 The base64 encode function in curl before version 7.51.0 is prone to a buffer being under allocated in 32bit systems if it receives at least 1Gb as input via `CURLOPT_USERNAME`.

CVE-2016-8618 SUSE Studio Onsite 1.3:libcurl-devel-7.19.7-1.20.47.2 moderate 5.1 AV:N/AC:H/Au:N/C:P/I:P/A:P To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2016/suse-su-20162700-1/ https://www.suse.com/security/cve/CVE-2016-8618.html CVE-2016-8618 https://bugzilla.suse.com/1005637 SUSE Bug 1005637 The function `read_data()` in security.c in curl before version 7.51.0 is vulnerable to memory double free.

CVE-2016-8620 SUSE Studio Onsite 1.3:libcurl-devel-7.19.7-1.20.47.2 low 1.9 AV:L/AC:M/Au:N/C:N/I:N/A:P To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2016/suse-su-20162700-1/ https://www.suse.com/security/cve/CVE-2016-8620.html CVE-2016-8620 https://bugzilla.suse.com/1005640 SUSE Bug 1005640 The `curl_getdate` function in curl before version 7.51.0 is vulnerable to an out of bounds read if it receives an input with one digit short.

Internally, even if this function would be made to allocate a unscape destination buffer larger than 2GB, it would return that new length in a signed 32 bit integer variable, thus the length would get either just truncated or both truncated and turned negative. That could then lead to libcurl writing outside of its heap based buffer.

This may have security implications if you for example use an URL parser that follows the RFC to check for allowed domains before using curl to request them.
