Description

This security bulletin contains information about 13 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2023-44487)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".

Note, the vulnerability is being actively exploited in the wild.


2) Out-of-bounds read (CVE-ID: CVE-2023-0800)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition within the tiffcrop() function in tools/tiffcrop.c. A remote attacker can pass a specially crafted TIFF file to the application, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.

3) Out-of-bounds read (CVE-ID: CVE-2023-0801)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition within the tiffcrop() function in tools/tiffcrop.c. A remote attacker can pass a specially crafted TIFF file to the application, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.

4) Out-of-bounds read (CVE-ID: CVE-2023-0802)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition within the tiffcrop() function in tools/tiffcrop.c. A remote attacker can pass a specially crafted TIFF file to the application, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.

5) Out-of-bounds write (CVE-ID: CVE-2023-0803)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the tiffcrop() function in tools/tiffcrop.c. A remote attacker can pass a specially crafted TIFF file to the application, trigger an out-of-bounds write and perform a denial of service (DoS) attack.


6) Out-of-bounds write (CVE-ID: CVE-2023-0804)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the tiffcrop() function in tools/tiffcrop.c. A remote attacker can pass a specially crafted TIFF file to the application, trigger an out-of-bounds write and perform a denial of service (DoS) attack.

7) Out-of-bounds read (CVE-ID: CVE-2023-4527)

The vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition within the getaddrinfo() function called with the AF_UNSPEC address family. A remote attacker with control over DNS server can send a DNS response via TCP larger than 2048 bytes, trigger an out-of-bounds read and crash the application or gain access to potentially sensitive information.

Successful exploitation of the vulnerability requires that system is configured with no-aaaa mode via /etc/resolv.conf.




8) Use-after-free (CVE-ID: CVE-2023-4806)

The vulnerability allows an attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error within the getaddrinfo() function. A remote attacker can perform a denial of service (DoS) attack.



9) Use-after-free (CVE-ID: CVE-2023-4813)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error within the gaih_inet() function when the getaddrinfo() function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.



10) Buffer overflow (CVE-ID: CVE-2023-4911)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to insufficient validation of GLIBC_TUNABLES environment variable. A local user can trigger memory corruption and execute arbitrary code with elevated privileges.

11) Improper input validation (CVE-ID: CVE-2023-22081)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The vulnerability exists due to improper input validation within the JSSE component in Oracle GraalVM for JDK. A remote non-authenticated attacker can exploit this vulnerability to perform service disruption.


12) Buffer overflow (CVE-ID: CVE-2023-29491)

The vulnerability allows a local user to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing malformed data in a terminfo database file. A local user can trigger memory corruption and execute arbitrary code on the target system.



13) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-30630)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to application does not properly impose security restrictions when executing the command with the "--dump-bin" option. A local user can overwrite arbitrary files on the system and escalate privileges.
