FreeBSD Information Disclosure Vulnerability (CNVD-2020-20732)

FreeBSD is a set of Unix-like operating systems from the FreeBSD Foundation. A security vulnerability exists in FreeBSD. A local attacker could exploit this vulnerability to obtain sensitive information...

PlayStation: Use-After-Free In IPV6_2292PKTOPTIONS leading To Arbitrary Kernel R/W Primitives

Summary Due to missing locks in option IPV62292PKTOPTIONS of setsockopt , it is possible to race and free the struct ip6pktopts buffer, while it is being handled by ip6setpktopt. This structure contains pointers ip6popktinfo that can be hijacked to obtain arbitrary kernel R/W primitives. As a...

FreeBSD : FreeBSD -- Kernel memory disclosure with nested jails (6b90acba-6a0a-11ea-92ab-00163e433440)

A missing NUL-termination check for the jailset2 configration option 'osrelease' may return more bytes when reading the jail configuration back with jailget2 than were originally set. Impact : For jails with a non-default setting of children.max 0 'nested jails' a superuser inside a jail can crea...

FreeBSD : FreeBSD -- Insufficient ixl(4) ioctl(2) privilege checking (b2b83761-6a09-11ea-92ab-00163e433440)

The driver-specific ioctl2 command handlers in ixl4 failed to check whether the caller has sufficient privileges to perform the corresponding operation. Impact : The ixl4 handler permits unprivileged users to trigger updates to the device's non-volatile memory NVM. C Tenable Network Security, Inc...

FreeBSD : FreeBSD -- Incorrect user-controlled pointer use in epair (0cc7e547-6a0a-11ea-92ab-00163e433440)

Incorrect use of a potentially user-controlled pointer in the kernel allowed vnet jailed users to panic the system and potentially execute aribitrary code in the kernel. Impact : Users with root level access or the PRIVNETIFCREATE privilege can panic the system, or potentially escape the jail or...

FreeBSD : FreeBSD -- TCP IPv6 SYN cache kernel information disclosure (0e06013e-6a06-11ea-92ab-00163e433440)

When a TCP server transmits or retransmits a TCP SYN-ACK segment over IPv6, the Traffic Class field is not initialized. This also applies to challenge ACK segments, which are sent in response to received RST segments during the TCP connection setup phase. Impact : For each TCP SYN-ACK or challeng...
