Cisco AMP for Endpoints and ClamAV Privilege Escalation Vulnerability

A vulnerability in the endpoint software of Cisco AMP for Endpoints and Clam AntiVirus could allow an authenticated, local attacker to cause the running software to delete arbitrary files on the system. The vulnerability is due to a race condition that could occur when scanning malicious files. An attacker with local shell access could exploit this vulnerability by executing a script that could trigger the race condition. A successful exploit could allow the attacker to delete arbitrary files on the system that the attacker would not normally have privileges to delete, producing system instability or causing the endpoint software to stop working.

ClamAV PDF Parsing Denial of Service Vulnerability

A vulnerability in the PDF archive parsing module in Clam AntiVirus (ClamAV) Software versions 0.101 - 0.102.2 could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to a stack buffer overflow read. An attacker could exploit this vulnerability by sending a crafted PDF file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process crash, resulting in a denial of service condition.

ClamAV ARJ Archive Parsing Denial of Service Vulnerability

A vulnerability in the ARJ archive parsing module in Clam AntiVirus (ClamAV) Software versions 0.102.2 could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to a heap buffer overflow read. An attacker could exploit this vulnerability by sending a crafted ARJ file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process crash, resulting in a denial of service condition.

An issue was discovered in Mbed TLS before 2.25.0 (and before 2.16.9 LTS and before 2.7.18 LTS). A NULL algorithm parameters entry looks identical to an array of REAL (size zero) and thus the certificate is considered valid. However, if the parameters do not match in any way, then the certificate should be considered invalid.

An issue was discovered in Mbed TLS before 2.24.0 (and before 2.16.8 LTS and before 2.7.17 LTS). There is missing zeroization of plaintext buffers in mbedtls_ssl_read to erase unused application data from memory.

An issue was discovered in Mbed TLS before 2.25.0 (and before 2.16.9 LTS and before 2.7.18 LTS). The calculations performed by mbedtls_mpi_exp_mod are not limited; thus, supplying overly large parameters could lead to denial of service when generating Diffie-Hellman key pairs.

An issue was discovered in Arm Mbed TLS before 2.24.0. mbedtls_x509_crl_parse_der has a buffer over-read (of one byte).

An issue was discovered in Arm Mbed TLS before 2.24.0. It incorrectly uses a revocationDate check when deciding whether to honor certificate revocation via a CRL. In some situations, an attacker can exploit this by changing the local clock.

An issue was discovered in Arm Mbed TLS before 2.24.0. An attacker can recover a private key (for RSA or static Diffie-Hellman) via a side-channel attack against generation of base blinding/unblinding values.

An issue was discovered in Arm Mbed TLS before 2.23.0. A remote attacker can recover plaintext because a certain Lucky 13 countermeasure doesn't properly consider the case of a hardware accelerator.

An issue was discovered in Arm Mbed TLS before 2.23.0. A side channel allows recovery of an ECC private key, related to mbedtls_ecp_check_pub_priv, mbedtls_pk_parse_key, mbedtls_pk_parse_keyfile, mbedtls_ecp_mul, and mbedtls_ecp_mul_restartable.

libwebp: excessive memory allocation when reading a file

A flaw was found in libwebp in versions before 1.0.1. When reading a file libwebp allocates an excessive amount of memory. The highest threat from this vulnerability is to the service availability.

libwebp: out-of-bounds read in ChunkAssignData() in mux/muxinternal.c

A flaw was found in libwebp in versions before 1.0.1. An out-of-bounds read was found in function ChunkAssignData. The highest threat from this vulnerability is to data confidentiality and to the service availability.

libwebp: out-of-bounds read in ChunkVerifyAndAssign() in mux/muxread.c

A flaw was found in libwebp in versions before 1.0.1. An out-of-bounds read was found in function ChunkVerifyAndAssign. The highest threat from this vulnerability is to data confidentiality and to the service availability.

libwebp: use-after-free in EmitFancyRGB() in dec/io_dec.c

A flaw was found in libwebp in versions before 1.0.1. A use-after-free was found due to a thread being killed too early. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

libwebp: heap-based buffer overflow in WebPDecode*Into functions

A flaw was found in libwebp in versions before 1.0.1. A heap-based buffer overflow in function WebPDecodeRGBInto is possible due to an invalid check for buffer size. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

kernel: fuse: fuse_do_getattr() calls make_bad_inode() in inappropriate situations

An issue was discovered in the FUSE filesystem implementation in the Linux kernel before 5.10.6, aka CID-5d069dbe8aaf. fuse_do_getattr() calls make_bad_inode() in inappropriate situations, causing a system crash. NOTE: the original fix for this vulnerability was incomplete, and its incompleteness is tracked as CVE-2021-28950.

kernel: infinite loop in set_memory_region_test in arch/x86/kvm/svm/svm.c for certain nested page faults

An issue was discovered in the Linux kernel before 5.8. arch/x86/kvm/svm/svm.c allows a set_memory_region_test infinite loop for certain nested page faults, aka CID-e72436bc3a52.

Redmine before 4.0.7 and 4.1.x before 4.1.1 allows attackers to discover the subject of a non-visible issue by performing a CSV export and reading time entries.

Redmine before 4.0.7 and 4.1.x before 4.1.1 has stored XSS via textile inline links.
