Vulnerabilities

A local privilege escalation vulnerability was found on polkit's pkexec utility.

NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow when handling DER-encoded DSA or RSA-PSS signatures.

An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through 14.0.

The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandles bounds checking.

sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows privilege escalation because supplemental groups are not initialized as expected.

The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.5 and 1.19.x before 1.19.3 has a NULL pointer dereference in kdc/do_tgs_req.c via a FAST inner body that lacks a server field.

An issue was discovered in the Linux kernel before 5.10.

An issue was discovered in the FUSE filesystem implementation in the Linux kernel before 5.10.6, aka CID-5d069dbe8aaf.

A flaw was found in RPM's signature check functionality when reading a package file.

SDL (Simple DirectMedia Layer) through 2.0.12 has an Integer Overflow (and resultant SDL_memcpy heap corruption) in SDL_BlitCopy in video/SDL_blit_copy.c via a crafted .BMP file.

A flaw memory leak in the Linux kernel performance monitoring subsystem was found in the way if using PERF_EVENT_IOC_SET_FILTER.

A flaw was found in the Linux kernel.

A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7.

In create_pinctrl of core.c, there is a possible out of bounds read due to a use after free.

A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file system, in the way it accesses a directory with broken indexing.

In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131.

chmd_read_headers in mspack/chmd.c in libmspack before 0.8alpha accepts a filename that has '\0' as its first or second character (such as the "/\0" name).

In mspack/cab.h in libmspack before 0.8alpha and cabextract before 1.8, the CAB block input buffer is one byte too small for the maximal Quantum block, leading to an out-of-bounds write.

Missing message authentication in the meta-protocol in Tinc VPN version 1.0.34 and earlier allows a man-in-the-middle attack to disable the encryption of VPN packets.

tinc 1.0.30 through 1.0.34 has a broken authentication protocol, although there is a partial mitigation.

tinc before 1.0.30 has a broken authentication protocol, without even a partial mitigation.

An exploitable code execution vulnerability exists in the XCF image rendering functionality of Simple DirectMedia Layer SDL2_image-2.0.2.

An exploitable information disclosure vulnerability exists in the PCX image rendering functionality of Simple DirectMedia Layer SDL2_image-2.0.2.
