What:
Fix: isiplocalnet() nasl function.
Jira: SC-1232
Close #1829

Why:
The function just check the first address in the network interface. This produces that if the target host is in the same network as a second address in a network interface returns a false negative.

E.g.: given the following config, if the target host has 192.168.10.100, the target was not recognize as in the same local network, because the local ip in the 192.168.10.0/24 is the second defined in the interface.

With this patch, all addresses in all interfaces are checked.

How:
See #1829 or set an interface with similar settings as above. Later run the following script again a target which belongs or not to the local network

is_local_net.nasl

display(this_host());
display(islocalnet());

sudo openvas-nasl -X -d -D -i $PLUGINSPATH is_local_net.nasl -t 192.168.1.1

Description

A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially crafted certificate, causing GnuTLS to become unresponsive or slow, resulting in a denial-of-service condition.

A flaw in libtasn1 causes inefficient handling of specific certificate data.

Remote packet capture support is disabled by default in libpcap.

One of the function arguments can be a filesystem path, which normally means a directory with input data files. When the specified path cannot be used as a directory, the function receives NULL from opendir(), but does not check the return value and passes the NULL value to readdir(), which causes a NULL pointer derefence.

EPSS Percentile30th percentile
Description

DISPUTEDA failure in the -fstack-protector feature in GCC-based toolchains that target AArch64 allows an attacker to exploit an existing buffer overflow in dynamically-sized local variables in your application without this being detected. This stack-protector failure only applies to C99-style dynamically-sized local variables or those created using alloca(). The stack-protector operates as intended for statically-sized local variables. The default behavior when the stack-protector detects an overflow is to terminate your application, resulting in controlled loss of availability. An attacker who can exploit a buffer overflow without triggering the stack-protector might be able to change program flow control to cause an uncontrolled loss of availability or to go further and affect confidentiality or integrity. NOTE: The GCC project argues that this is a missed hardening bug and not a vulnerability by itself.

Affected range>=1.10.1-3
Fixed versionNot Fixed
EPSS Score0.33%
EPSS Percentile71st percentile
Description

cipher/elgamal.c in Libgcrypt through 1.8.2, when used to encrypt messages directly, improperly encodes plaintexts, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for Libgcrypt's ElGamal implementation.

Fixed versionNot Fixed
EPSS Score0.05%
EPSS Percentile20th percentile
Description

A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support. The Readline library uses an "INPUTRC" environment variable to get a path to the library config file. When the library cannot parse the specified file, it prints an error message containing data from the file. This flaw allows an unprivileged user to read root-owned files, potentially leading to privilege escalation. This flaw affects util-linux versions prior to 2.37.4.

Fixed versionNot Fixed
EPSS Score0.07%
EPSS Percentile31st percentile
Description

OpenSSL 0.9.8i on the Gaisler Research LEON3 SoC on the Xilinx Virtex-II Pro FPGA uses a Fixed Width Exponentiation (FWE) algorithm for certain signature calculations, and does not verify the signature before providing it to a caller, which makes it easier for physically proximate attackers to determine the private key via a modified supply voltage for the microprocessor, related to a "fault-based attack."

EPSS Percentile27th percentile
Description

ifconfig, when used on the Linux kernel 2.2 and later, does not report when the network interface is in promiscuous mode if it was put in promiscuous mode using PACKET_MR_PROMISC, which could allow attackers to sniff the network without detection, as demonstrated using libpcap.

  • net-tools (unimportant)
    This seems to be a misunderstanding of what the PROMISC flag
    is about. ifconfig reports properly when it is set using
    "ifconfig promisc".

Description

Tar 1.15.1 does not properly warn the user when extracting setuid or setgid files, which may allow local users or remote attackers to gain privileges.

This is intended behaviour, after all tar is an archiving tool and you
need to give -p as a command line flag

EPSS Score0.16%
EPSS Percentile53rd percentile
Description

GLib 2.31.8 and earlier, when the g_str_hash function is used, computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table. NOTE: this issue may be disputed by the vendor; the existence of the g_str_hash function is not a vulnerability in the library, because callers of g_hash_table_new and g_hash_table_new_full can specify an arbitrary hash function that is appropriate for the application.

Description

In GNU Coreutils through 8.29, chown-core.c in chown and chgrp does not prevent replacement of a plain file with a symlink during use of the POSIX "-R -L" options, which allows local users to modify the ownership of arbitrary files by leveraging a race condition.

Description

initscripts in rPath Linux 1 sets insecure permissions for the /var/log/btmp file, which allows local users to obtain sensitive information regarding authentication attempts. NOTE: because sshd detects the insecure permissions and does not log certain events, this also prevents sshd from logging failed authentication attempts by remote attackers.
