Kerberos 5 (aka krb5) 1.21.2 contains a memory leak vulnerability in /krb5/src/kdc/ndr.c.
GNU Binutils before 2.40 was discovered to contain an excessive memory consumption vulnerability via the function bfddwarf2findnearestlinewithalt at dwarf2.c. The attacker could supply a crafted ELF file and cause a DNS attack.
GNU Binutils before 2.40 was discovered to contain a memory leak vulnerability var the function findabstractinstance in dwarf2.c.
A stack overflow was discovered in the TIFFVGetField function of Tiffsplit v4.4.0. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted TIFF file parsed by the "tiffsplit" or "tiffcrop" utilities.
GnuPG through 2.3.6, in unusual situations where an attacker possesses any secret-key information from a victim's keyring and other constraints (e.g., use of GPGME) are met, allows signature forgery via injection into the status line.
Accelerate Framework. A memory consumption issue was addressed with improved memory handling.
LibTIFF master branch has an out-of-bounds read in LZWDecode in libtiff/tiflzw.c:624, allowing attackers to cause a denial-of-service via a crafted tiff file. For users that compile libtiff from sources, the fix is available with commit b4e79bfa.
A stack buffer overflow flaw was found in Libtiffs' tiffcp.c in main() function. This flaw allows an attacker to pass a crafted TIFF file to the tiffcp tool, triggering a stack buffer overflow issue, possibly corrupting the memory, and causing a crash that leads to a denial of service.
A vulnerability classified as problematic was found in LibTIFF 4.3.0. Affected by this vulnerability is the TIFF File Handler of tiff2ps. Opening a malicious file leads to a denial of service. The attack can be launched remotely but requires user interaction. The exploit has been disclosed to the public and may be used.
A flaw was found in the libvirt nwfilter driver. The virNWFilterObjListNumOfNWFilters method failed to acquire the driver->nwfilters mutex before iterating over virNWFilterObj instances. There was no protection to stop another thread from concurrently modifying the driver->nwfilters object. This flaw allows a malicious, unprivileged user to exploit this issue via libvirt's API virConnectNumOfNWFilters to crash the network filter management daemon (libvirtd/virtnwfilterd).
Unchecked Return Value to NULL Pointer Dereference in tiffcrop in libtiff 4.3.0 allows attackers to cause a denial-of-service via a crafted tiff file. For users that compile libtiff from sources, the fix is available with commit f2b656e2.
Divide By Zero error in tiffcrop in libtiff 4.3.0 allows attackers to cause a denial-of-service via a crafted tiff file. For users that compile libtiff from sources, the fix is available with commit f8d0f9aa.
Out-of-bounds Read error in tiffcp in libtiff 4.3.0 allows attackers to cause a denial-of-service via a crafted tiff file. For users that compile libtiff from sources, the fix is available with commit 408976c4.
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.
DISPUTED A Memory Leak vulnerability exists in SQLite Project SQLite3 3.35.1 and 3.37.0 via maliciously crafted SQL Queries (made via editing the Database File), it is possible to query a record, and leak subsequent bytes of memory that extend beyond the record, which could let a malicious user obtain sensitive information. NOTE: The developer disputes this as a vulnerability stating that If you give SQLite a corrupted database file and submit a query against the database, it might read parts of the database that you did not intend or expect.
LibTIFF is vulnerable to a denial of service, caused by a NULL pointer dereference in the memcpy() function in TIFFReadDirectory() in tifdirread.c. A local authenticated attacker could exploit this vulnerability to cause a denial of service.
LibTIFF is vulnerable to a denial of service, caused by a NULL pointer dereference in memcpy() function in TIFFFetchStripThing() in tifdirread.c. A local authenticated attacker could exploit this vulnerability to cause a denial of service.
LibTIFF 4.3.0 has an out-of-bounds read in TIFFmemcpy in tifunix.c in certain situations involving a custom tag and 0x0200 as the second word of the DE field.
A flaw was found in the libvirt libxl driver. A malicious guest could continuously reboot itself and cause libvirtd on the host to deadlock or crash, resulting in a denial of service condition.
Buffer Overflow in LibTiff v4.0.10 allows attackers to cause a denial of service via the 'in TIFFmemcpy' funtion in the component 'tifunix.c'.
A flaw was found in grub2 when handling a PNG image header. When decoding the data contained in the Huffman table at the PNG file header, an out-of-bounds write may happen on grub's heap.
A flaw was found in the libvirt virStoragePoolLookupByTargetPath API. The storagePoolLookupByTargetPath() function does not properly release a locked object (virStoragePoolObj) on ACL permission failure. Clients connecting to the read-write socket with limited ACL permissions could use this flaw to acquire the lock and prevent other users from accessing storage pool/volume APIs, resulting in a denial of service condition.

GNU Wget through 1.21.1 does not omit the Authorization header upon a redirect to a different origin, a related issue to CVE-2018-1000007.
A flaw was found in libvirt while it generates SELinux MCS category pairs for VMs' dynamic labels. This flaw allows one exploited guest to access files labeled for another guest, resulting in the breaking out of sVirt confinement. The highest threat from this vulnerability is to confidentiality and integrity.
GNU C Library (aka glibc or libc6) is vulnerable to a denial of service, caused by an error when processing some invalid inputs from several IBM character sets in the iconv function. By sending invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, IBM1399 encodings, a local authenticated attacker could exploit this vulnerability to cause the application to enter into an infinite loop.
A flaw was found in libtiff 4.1.0 and before. Due to a memory allocation failure in tifread.c, a crafted TIFF file can lead to an abort, resulting in denial of service.
This is a different flaw from CVE-2020-35521
