CVE-2019-3812 created at 25 Sep 2019 19:31:40
Severity
+ High
Remote
+ Local
Type
+ Arbitrary code execution
Description
+ QEMU, through version 2.10 and through version 3.1.0, is vulnerable to an out-of-bounds read of up to 128 bytes in the hw/i2c/i2c-ddc.c:i2c_ddc() function. A local attacker with permission to execute i2c commands could exploit this to read stack memory of the qemu process on the host.

Type
+ Arbitrary code execution
Description
+ Spice, versions 0.5.2 through 0.14.1, are vulnerable to an out-of-bounds read due to an off-by-one error in memslot_get_virt. This may lead to a denial of service, or, in the worst case, code-execution by unauthenticated attackers.

+ Remote
Type
+ Authentication bypass
Description
+ A vulnerability has been found in Dovecot versions prior to 2.3.4.1, allowing a remote client in possession of a trusted SSL certificate to log in as any user, in some configurations.
+ This affects only installations using auth_ssl_require_client_cert = yes and auth_ssl_username_from_cert = yes, and the the attacker might have access to a trusted certificate without the ssl_cert_username_field (default to commonName) set in it.

CVE-2019-3822 created at 25 Sep 2019 19:31:40
Severity
+ High
Remote
+ Remote
Type
+ Arbitrary code execution
Description
+ libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large "nt response" data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server. Such a "large value" needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.

CVE-2019-3823 created at 25 Sep 2019 19:31:40
Severity
+ High
Remote
+ Remote
Type
+ Arbitrary code execution
Description
+ libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to `smtp_endofresp()` isn't NUL terminated and contains no character ending the parsed number, and `len` is set to 5, then the `strtol()` call reads beyond the allocated buffer. The read contents will not be returned to the caller.

Type
+ Arbitrary code execution
Description
+ A critical memory corruption vulnerability has been found in GnuTLS versions prior to 3.6.7, in any API backed by verify_crt(), including gnutls_x509_trust_list_verify_crt() and related routines. Any client or server that verifies X.509 certificates with GnuTLS is likely affected and can be compromised by a malicious server or active network attacker.
