A use-after-free vulnerability was found in systemd. This issue occurs due to the onstreamio() function and dnsstreamcomplete() function in 'resolved-dns-stream.c' not incrementing the reference counting for the DnsStream object. Therefore, other functions and callbacks called can dereference the DNSStream object, causing the use-after-free when the reference is still used later.
IBM Security Guardium 11.2 does not require that users should have strong passwords by default, which makes it easier for attackers to compromise user accounts. IBM X-Force ID: 196279.
IBM Security Guardium 11.2 contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data. IBM X-Force ID: 196313.
IBM Security Guardium 11.2 could allow a remote authenticated attacker to execute arbitrary commands on the system. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary commands on the system. IBM X-Force ID: 195766.
An issue was discovered in http/ContentLengthInterpreter.cc in Squid before 4.12 and 5.x before 5.0.3. A Request Smuggling and Poisoning attack can succeed against the HTTP cache. The client sends an HTTP request with a Content-Length header containing "+\ "-" or an uncommon shell whitespace character prefix to the length field-value.
IBM Security Guardium 11.1 could allow a remote authenticated attacker to execute arbitrary commands on the system. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary commands on the system. IBM X-Force ID: 174735.
cURL libcurl is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the tftpreceivepacket function. By sending specially-crafted request containing an OACK without the BLKSIZE option, a remote attacker could overflow a buffer and execute arbitrary code on the system.
A flaw was discovered in dbus where the implementation of DBUSCOOKIESHA1 is susceptible to a symbolic link attack. A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink to cause the DBusServer to read and write in unintended locations. This could result in authentication bypass.
filecopyfallback in gio/gfile.c in GNOME GLib 2.15.0 through 2.61.1 creates new files with default permissions and set the correct permissions after the operation is finished. This might cause that the files can be accessible by more users during the operation than expected.
