In the Linux kernel, the following vulnerability has been resolved:
A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process.
A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service.
A flaw was found in the Samba printing subsystem. Samba passes the client-controlled job description string to the command configured with the "print command" setting via the "%J" substitution character without escaping shell meta characters. A remote attacker could exploit this vulnerability by sending a specially crafted print job description that contains unescaped shell characters. This could lead to remote code execution on the affected system.
A flaw was found in libarchive. On 32-bit systems, an integer overflow vulnerability exists in the zisofs block pointer allocation logic. A remote attacker can exploit this by providing a specially crafted ISO9660 image, which can lead to a heap buffer overflow. This could potentially allow for arbitrary code execution on the affected system.
A flaw was found in GIMP's PSD file format plugin. This vulnerability, an unsigned integer underflow in the blockrem variable, occurs when a user opens a specially crafted .psd image file. The underflow leads to parser confusion, enabling an attacker to inject arbitrary data as layer resource blocks. This can ultimately result in arbitrary code execution, allowing the attacker to run malicious code on the victim's system.

NGINX ngxhttpproxyv2module and ngxhttpgrpcmodule vulnerability
A flaw was found in GLib. A state confusion issue exists in gdbusnodeinfonewforxml() in the gio/gdbusintrospection.c file when processing malformed D-Bus introspection XML, specifically with a node element nested within other elements like method, signal, property or arg. This issue can cause an unsigned integer overflow and lead to an out-of-bounds read, resulting in a denial of service.
A buffer-underflow vulnerability exists in GLib’s GVariant parser, specifically within bytestringparse() and stringparse(). The parser uses signed 32-bit integers (gint) as loop indices (i and j). When extremely large strings are parsed, these counters overflow into negative values, causing the parser to write to memory before the start of the allocated buffer (str[j++]). This results in a classic out-of-bounds write condition. Because GVariant parsing is often performed on attacker-influenced data, a remote attacker can trigger heap corruption, causing a crash or potentially achieving code execution. This flaw has been confirmed by maintainers and patched upstream.
A flaw was found in FreeIPA. When a trust relationship is configured between FreeIPA and Active Directory, Active Directory users can bypass authentication for FreeIPA services, including the portal, SMB server, and LDAP directory. This is possible by impersonating a client name in the Ticket Granting Service (TGS) due to FreeIPA services not verifying Privilege Attribute Certificate (PAC) certificates. This vulnerability could allow an authenticated Active Directory user to escalate their privileges within the FreeIPA domain.
A vulnerability identified in NetIQ Advance Authentication that leaks sensitive server information. This issue affects NetIQ Advance Authentication version before 6.3.5.1
A crafted request uri-path can cause modproxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier.
A Polymorphic Typing issue was discovered in FasterXML jackson-databind before 2.9.10, 2.8.11.5, and 2.6.7.3. It is related to com.zaxxer.hikari.HikariDataSource. This is a different vulnerability than CVE-2019-14540.
A flaw was discovered in FasterXML jackson-databind, where it would permit polymorphic deserialization of malicious objects using the ehcache and logback JNDI gadgets when used in conjunction with polymorphic type handling methods such as enableDefaultTyping() or when @JsonTypeInfo is using Id.CLASS or Id.MINIMALCLASS or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. An attacker could use this flaw to execute arbitrary code.
AssertionConsumerServiceURL is a Java implementation for SAML Service Providers (org.keycloak.protocol.saml). Affected versions of this package are vulnerable to Cross-site Scripting (XSS).
AssertionConsumerServiceURL allows XSS when sending a crafted SAML XML request.
A flaw was found in libmicrohttpd. A missing bounds check in the postprocessurlencoded function leads to a buffer overflow, allowing a remote attacker to write arbitrary data in an application that uses libmicrohttpd. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Only version 0.9.70 is vulnerable.
apachemodphp. Multiple issues were addressed by updating to PHP version 7.3.11.
A flaw was found in the Linux kernel. A heap based buffer overflow in mwifiexuapparsetailies function in drivers/net/wireless/marvell/mwifiex/ie.c might lead to memory corruption and possibly other consequences.
In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfsrq's, which allows attackers to cause a denial of service (infinite loop in updateblockedaverages) or possibly have unspecified other impact by inducing a high load.
A flaw was found in the X.Org X server. This vulnerability, an out-of-bounds read, affects the XKB (X Keyboard Extension) modifier map handling. An attacker with access to the X11 server can exploit this by sending a malformed request, which causes the server to read beyond its intended memory boundaries. This can lead to the exposure of sensitive information or cause the server to crash, resulting in a denial of service.
A flaw was found in the X.Org X server. This out-of-bounds read vulnerability in the XKB geometry processing, specifically within the CheckSetGeom() and XkbAddGeomKeyAlias functions, allows an attacker to read uninitialized or out-of-bounds memory. An attacker with a connection to the X11 server, either locally or remotely, can exploit this without user interaction. This could lead to the disclosure of memory contents or cause a denial of service by crashing the server.
A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.10. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the commons-dbcp (1.4) jar in the classpath, and an attacker can find an RMI service endpoint to access, it is possible to make the service execute a malicious payload. This issue exists because of org.apache.commons.dbcp.datasources.SharedPoolDataSource and org.apache.commons.dbcp.datasources.PerUserPoolDataSource mishandling.
A Polymorphic Typing issue was discovered in FasterXML jackson-databind before 2.9.10, 2.8.11.5, and 2.6.7.3. It is related to com.zaxxer.hikari.HikariConfig.
A flaw was found in jackson-databind before 2.9.10. New serialization gadgets were found regarding a class of the ehcache package which may help in exploiting deserialization issues.

A flaw was found in libnbd. A server can reply with a block size larger than 2^63 (the NBD spec states the size is a 64-bit unsigned value). This issue could lead to an application crash or other unintended behavior for NBD clients that doesn't treat the return value of the nbdgetsize() function correctly.
