ntp: DoS on client ntpd using server mode packet

ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp.

httpd: mod_http2 concurrent pool usage

Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers.

openldap2: /usr/lib/openldap/start allows ldap user/group to recursively chown arbitrary directory trees to itself

A Untrusted Search Path vulnerability in openldap2 of openSUSE Factory allows local attackers with control of the ldap user or group to change ownership of arbitrary directory entries to this user/group, leading to escalation to root. This issue affects: openSUSE Factory openldap2 versions prior to 2.6.3-404.1.

libuv: buffer overflow in realpath

The implementation of realpath in libuv < 10.22.1, < 12.18.4, and < 14.9.0 used within Node.js incorrectly determined the buffer size which can result in a buffer overflow if the resolved path is longer than 256 bytes.

nodejs: HTTP request smuggling due to CR-to-Hyphen conversion

Node.js < 12.18.4 and < 14.11 can be exploited to perform HTTP desync attacks and deliver malicious payloads to unsuspecting users. The payloads can be crafted by an attacker to hijack user sessions, poison cookies, perform clickjacking, and a multitude of other attacks depending on the architecture of the underlying system. The attack was possible due to a bug in processing of carrier-return symbols in the HTTP header names.

nodejs: HTTP header values do not have trailing optional whitespace trimmed

Including trailing white space in HTTP header values in Nodejs 10, 12, and 13 causes bypass of authorization based on header value comparisons

nodejs: HTTP request smuggling using malformed Transfer-Encoding header

HTTP request smuggling in Node.js 10, 12, and 13 causes malicious payload delivery when transfer-encoding is malformed

nodejs: Remotely trigger an assertion on a TLS server with a malformed certificate string

Improper Certificate Validation in Node.js 10, 12, and 13 causes the process to abort when sending a crafted X.509 certificate

cairo: Out-of-bounds read due to mishandling of unexpected malloc(0) call

cairo-truetype-subset.c in cairo 1.15.6 and earlier allows remote attackers to cause a denial of service (out-of-bounds read) because of mishandling of an unexpected malloc(0) call.

libcroco: Memory allocation failure in the cr_tknzr_parse_comment function

The cr_tknzr_parse_comment function in cr-tknzr.c in libcroco 0.6.12 allows remote attackers to cause a denial of service (memory allocation error) via a crafted CSS file.

libcroco: Infinite loop in the cr_parser_parse_selector_core function

The cr_parser_parse_selector_core function in cr-parser.c in libcroco 0.6.12 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a crafted CSS file.

golang: Elliptic curves carry propagation issue in x86-64 P-256

A bug in the standard library ScalarMult implementation of curve P-256 for amd64 architectures in Go before 1.7.6 and 1.8.x before 1.8.2 causes incorrect results to be generated for specific input points. An adaptive attack can be mounted to progressively extract the scalar input to ScalarMult by submitting crafted points and observing failures to the derive correct output. This leads to a full key recovery attack against static ECDH, as used in popular JWT libraries.

git: Escape out of git-shell

git-shell in git before 2.4.12, 2.5.x before 2.5.6, 2.6.x before 2.6.7, 2.7.x before 2.7.5, 2.8.x before 2.8.5, 2.9.x before 2.9.4, 2.10.x before 2.10.3, 2.11.x before 2.11.2, and 2.12.x before 2.12.3 might allow remote authenticated users to gain privileges via a repository name that starts with a - (dash) character.

sane-backends: SANE_NET_CONTROL_OPTION response packet may contain memory contents of the server

saned in sane-backends 1.0.25 allows remote attackers to obtain sensitive memory information via a crafted SANE_NET_CONTROL_OPTION packet.

The ssh_agent_channel_data function in PuTTY before 0.68 allows remote attackers to have unspecified impact via a large length value in an agent protocol message and leveraging the ability to connect to the Unix-domain socket representing the forwarded agent connection, which trigger a buffer overflow.

The transit path validation code in Heimdal before 7.3 might allow attackers to bypass the capath policy protection mechanism by leveraging failure to add the previous hop realm to the transit path of issued tickets.

The AliasHandler component in PostfixAdmin before 3.0.2 allows remote authenticated domain admins to delete protected aliases via the delete parameter to delete.php, involving a missing permission check.

Cross-site scripting (XSS) vulnerability in the nav_path function in lib/viewvc.py in ViewVC before 1.0.14 and 1.1.x before 1.1.26 allows remote attackers to inject arbitrary web script or HTML via the nav_data name.

gnutls: Double-free while decoding crafted X.509 certificates

Double free vulnerability in the gnutls_x509_ext_import_proxy function in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allows remote attackers to have unspecified impact via crafted policy language information in an X.509 certificate with a Proxy Certificate Information extension.

gnutls: Out of memory while parsing crafted OpenPGP certificate

The stream reading functions in lib/opencdk/read-packet.c in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allow remote attackers to cause a denial of service (out-of-memory error and crash) via a crafted OpenPGP certificate.
