Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2014-9709)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in The GetCode_ function in gd_gif_in.c in GD 2.1.1 and earlier, as used in PHP before 5.5.21 and 5.6.x before 5.6.5,. A remote attacker can perform a denial of service (buffer over-read and application crash) via a crafted GIF image that is improperly handled by the gdImageCreateFromGif function.
2) NULL pointer dereference (CVE-ID: CVE-2015-1352)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dreference error in pgsql.c in the PostgreSQL (aka pgsql) extension in PHP through 5.6.7 does not validate token extraction for table names, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a specially crafted name. A remote attacker can perform a denial of service (DoS) attack.
3) Use-after-free error (CVE-ID: CVE-2015-2301)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to use-after-free vulnerability in the phar_rename_archive function in phar_object.c in PHP before 5.5.22 and 5.6.x before 5.6.6. A remote attacker can trigger memory corruption via vectors that trigger an attempted renaming of a Phar archive to the name of an existing file and cause the service to crash.
4) Buffer over-read (CVE-ID: CVE-2015-2783)
The vulnerability allows a remote attacker to obtain potentially sensitive information or cause DoS condition on the target system.The weakness exists due to buffer over-read in ext/phar/phar.c in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8. A remote attacker can obtain sensitive information from process memory or cause a denial of service via a crafted length value in conjunction with crafted serialized data in a phar archive, related to the phar_parse_metadata and phar_parse_pharfile functions.
5) Stack-based buffer overflow (CVE-ID: CVE-2015-3329)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists due to multiple stack-based buffer overflows in the phar_set_inode function in phar_internal.h in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8. A remote attacker can trigger memory corruption and execute arbitrary code via a crafted length value in a (1) tar, (2) phar, or (3) ZIP archive.
